bros no vex o...but wat type of questions were asked...pls am just tryin to learn

Am not a fresh graduate, I have over 4 years experience on pumps, valves and compressors and am currently working, they even ask me to come with my current payslip.

The questions were mainly on pumps, valves and other related oil and gas equipment

tpiadotcom:
it depends on what type of demographic they are looking for, or which demographic they want to reach.

it seems somewhere like google, for example, hires mostly younger, single and maybe nerdy/party loving types.

however, the movie I watched recently, showcased an employer who was looking for someone with a high debt profile, family oriented and mature.

so, it depends.

The position is a matured position of 4 to 5 years experience and is more of supervising. Is an engineering field and he answer 85% of the technical question correctly

Jobs/Vacancies › Re: Things Interviewers Say That Confirm You Won't Get An Offer by babacha: 4:28pm On Apr 27, 2015

My brother went for interview last week, at the end of the interview after salary discussion, the head of the panel ask him if he is married, how many children he have and where the family leave. He then told him u will hear from us and other members of the panel shake his hand and told him we enjoy ur presentation.
They spend more time with him more than the other 5 candidates. They were just 6 in number

Please what can u say on that reaction? Is it positive? I want ur comment pls

‎It dosent really go down well with me when pple voice their opinion authoritatively as if it's fact. We conducted the tests and the results came out within months. We could have been almost through with the interviews if not for some unknown factor. That alone has defied the status quo. U should expect more surprises.

Bros NNPC aptitude test result always come out within few months after the test, our case was not new. 2010 set finished interview Augus 2011 but they get offer letter in July 2012. From when they finished interview to when they get offer letter take one year. Unknown fator ends 2008 recruitment half way, now unknown factor has suspended 2012 recruitment again, we pray for the best but don't be too positive cos u will be disappointed if things do not happen as u expected

Well from one level to another in terms of promotions takes 3 years- just like it is with the IOCs (even though they are more reliant on performance than NNPC). So it should not come to you as an aberration that each recruitment will take 3 years seeing that the last set of GTs would be 3 years old this 2015 and therefore due for that promotion.

I strongly believe the recruitment process will end this year. I would be gravely surprised if it extends beyond this year. Even when the advert placement came out in 2012, I was certain the recruitment process would be consummated in 2015.

Just a hunch. (And yes I know hunches are bad for the back)

We wait, every one of us want it quick just that we don't have control over the situation. We don't need to expect too much from them so that we don't feel disappointed, is beta to expect less and get a surprise from them, anytin can happen in NNPC. They recruit 2006 and guys who apply 2008 were hoping to get a job in 2009 which is about 3 years from 2006 but notin happen. Let's wait and see what they will do this time

Not really. The process has always been 3 years from application to offer letter. It is almost a tradition. You can call "those people you know" and they would tell you.

Is not a tradition that it always take 3 years. 2005/2006 set take even less 2 years. If not for the change in GMD, 2010 would have even stay longer, it was the new GMD that ask for letters to be send out to successful candidates. NNPC recruitment don't have a time frame.
Even if they call for interview this year, they cannot send offer letter this year and induction and training beging this year, NNPC is not a private company that do things quickly.

In 2012 NNPC advertised and we apply.

In 2013 NNPC send notice to those who did not complete their application to complete it

In 2014 NNPC invite for test and we took the test

In 2015 NNPC send notice to those who pass the test

Looking at it carefully, we have one activity per year. Hope it won't follow that

In 2016 NNPC will call for interview and we will do the interview

In 2017 offer letter

In 2018 induction and training

We dey wait for dem, any time they want, make dem call us. Life continue

Edunwa302:
If the plugs were fired in numerical order from one end to the other, the successive power impulses from the pistons would cause the engine to run very unevenly and vibrate excessively.

In a four-cylinder engine, vibration is reduced with a firing order 1, 3, 4, 2 or 1, 2, 4, 3.

To add, the crankshaft is an irregular shape object, the piston are all attached to it, to avoid vibration, the crankshaft must be balance dynamically when rotating. That is why u see piston 1 and 4 moving together and only one can fire at a time and piston 2 and 3 moving together and only one can fire at a time
For 6 cylinder engine, piston 1 and 6 move together, piston 2 and 5 move together and piston 3 and 4 move together and that balance the rotation of the crankshaft dynamically. That is why the firing order of 6 cylinder engine can be 1,2,3,6,5,4 or 1,5,3,6,2,4 etc. Once u understand that ur crankshaft has to be balance dynamically and how the piston must move to balance it, den u can chose a firing order as a designer. The same principle apply to 8 and 12 cylinder V-engine

Oga pls there's OK? , all internal combustion engine(4stroke/2stroke engine) makes use of diesel or petrol the different is just the injection system which is either compression injestion system or spark injection system.
Its not only heavy duty engine dt runs on diesel, some keke en family size generating set which are two stroke power engines use desiel dt u v nt seen doesn't mean there's none thank you

I work on heavy duty and rotating equipments and I have not seen 2 stroke engine using diesel, it seems possible theoretically but practically, I have not seen. Even in small size family gen I have seen 2 stroke engine using petrol, I don't know of keke. U can tell us the name of the manufacturer of the 2 stroke engine u have seen using diesel. Am not doubting u cos not all engine I have seen but u can tell us the name of the one u have seen to be more sure.
If at all it exist, it must be a very small engine

GeneralSnipper:
Oga! Get it clear, there are four stroke petrol engines that use carburetor. Look for an old Peugeot 504 engine and you'll see it. We are all here to learn bro..........

I can see you have some good mechanical knowledge, nice one. Here are some questions for your attention

1.) If an engine is not designed to be water cooled (i.e. no radiator) what other means can be used to cool it? Explain the principle behind it.

2.) Why does a two stroke engine generates more smoke than a four stroke engine?

3.) A pump comes alive when powered on but it's not pumping, what could be the problem?

We no dey challeng ourselves, we are sharing idea, throw ur question to the house not me, but let me answer ur questions.
1, Engine are iether cool with liquid or air, if there is no radiator, u use air. But there is a major disadvantage. Air has a low heat density so if the speed of ur air is low, it can only carry a small mass of heat.

2, 2 stroke engine smoke more because they burn oil. Mind u, 4 stroke engine can also produce excess smoke if the piston ring is bad. To add more, these are what causes engine to smoke
Black smoke- if ur air/fuel ratio is imbalance, ie too much fuel in the combustion chember or less air in the chember
White smoke-incomplete combustion
Blue smoke-ur engine is burning oil, ie ur piston ring is bad and oil is entering the combustion chemberl

3 a pump can be runing but not pumping due to any of the following
1, If the suction pipe is not completly filled with liquid
2, If air is leaking into the suction pipe
3, If air is leaking into the pump
4, If ur foot valve is blucked
5, If ur suction pipe is not fully submerged
6, If ur empeller is mounted wrongly
7, If ur pump is not prime
8 etc

Bro...I still dont understand bro...I need aw Uare to relate d velocity of a body in a circular path with d angle of an inlet and discharge outlets of centrifugal pump...Thanks Bro!

If u use ur hand to spin water that is inside bucket, u will observe that the water will move away from the center of the bucket to the edge creating a vacuum at the center. That is what centrifugal pump does, the empeller spin the fluid and a vacuum is created at the center of the empeller for more fluid to come in. That is why u have ur suction at the center of the empeller.
From simple harmonic motion, the velocity of object in circular part is usually tangential to the circumference, that is why the discharge is always tangential to a particular point on the circumference of the empeller.

Draw a circle, draw a tangential Line to any point on the circumference of the circle, from the point of tangent, draw a line to the center of the circle. Ur 90 degree will appear. The tangential line is the discharge and the center of ur circle is the suction.
Hope is clear?

You're not seeing your mistake. 4 stroke engines can either be CI (diesel) or SI (gasoline/etrol). It seems what you believe is 4 stroke engines are mainly diesel consuming. Car engine is 4 stroke and some run on diesel, others on petrol.
Get it?

Those petro car that u talk about use injector, do u know?

Petro is liquid, u can't compress it

Let me tell u how the air move, from outside to the air filter, from air filter to inlet manifold, from inlet manifold to inlet valve, from inlet vale to chember,

Bros we are all learning, this is practical not theory,
If u tell me the point they mix and the component that mix them, I will agree

Bro, do your research adequately before posting here so as not to mis-educate people. To start with, liquids can be compressed due to the weak inter-molecular forces between them. 2: four-stroke engines could be of diesel or gasoline. The difference is that in a diesel, combustion occurs by just compression of the fuel-air mixture. In a gasoline engine, combustion occurs via spark plugs. This is why diesel engines are said to have a higher thermal efficiency than gasoline engines. The heat generated during compression alone is enough to bring about combustion.

Let me tell u how the fuel or diesel move in 4 stroke engine

From the tank, the fuel move along the hose to the primary fuel filter, from the primary it move to the secondary fuel filter (if the engine has two fuel filter), from the fuel filter to the injector pump, from injector pump to nozzle, from nozzle to combustion chember,.
If air should enter ur fuel line, ur fuel pump will not work effectivly and ur engine will go off. That is why mechanic bleed the fuel line to remove any air trap.
So fuel and air no dey mix with 4 stroke engine before they enter the chember

Go to a mechanic workshop and ask..

There is no 2 stroke engine that use diesel,
Also ask them if air and fuel are mixed before they enter the combustion chember.

This in not theory but practical, u can go and read more

Also the compressibility of liquid is so small that is regarded as incompressible, visit ur fluid mechnics text book again.

I have one question for u, can u tell us which component mix the air and diesel before they enter the combustion chember? I never see diesel engine with carburator
Another question for u, what is the need of compressing the fuel?
Bros go look heavy duty diesel engine very well before u argue. Fuel and diesel meet only at the combustion chember

2 stroke engine has carburator that mix ur air and petrol but 4 stroke engine do not have carburator.
4 stroke, ur turbo charger suck in air and only the air enter through the inlet valve while ur injector and nozzle break down the fuel to a form of gas and they enter from the nozzle.
That is why they call diesel Automotive gas oil (A G O) cos the injector and nossle break it down to gas form and as the nozzle spray it into the compressed air that is already hot, combustion take place

Good analysis. However you should note that in a 4-stroke engine, like in a 2-stroke in engine, it is the fuel-air mixture (not only the air) that enters the piston during the intake stroke and is compressed.

Bros in 4 stroke engine, is not the mixture of air and fuel that enter combustion chember, 4 stroke engine
are diesel engine, u don't have any 2 stroke engine that is diesel.
4 stroke engine, air enter first, after the air has been compressed, then the nezzle spray in diesel in form of gas into the combustion chember. That is why u don't have nozzle in 2 stroke engine because the mixture of air and fuel enter the chember from the inlet valve.
But in 4 stroke engine, only air enter the chember from the inlet valve and fuel enter from the nozzle. So they don't mix before they enter
U compress air to make it hot, u don't compress fuel, fuel is liquid and air is gas

Pls I'm not an English teacher ooo and I'm not forming one.I just like that Ur question as it interest me as a Mechanical Engineer.I want to try providing an answer...
The Suction and discharge at 90degree should be because each turn of d valve is a quarter.so the opening and closing of the outlets is 90degree.

The answer is in ur simple harmonic motion, just go back and look at ur simple harmonic motion, especially the velocity of an object in a circular path, then u will understand it more clear why the suction and discharge of a centrifugal pump are usually 90degree but if u still don't understand, we can share it togther here
