sorry maan

No sector of the economy is spared, yet people are clapping for the same government. That singular ungauded statement *fuel subsidy is gone* without any plans on ground was the beginning of all this chaos we are seeing every where. Incompetence shhhh........

Most times people make unguarded comment saying it is good for the officer and all what not, without knowing the terrain. It is not frustration or anything of such. If you have stayed in Benin before you will agree with me that the Edo state traffic officers are one of the most lenient guys nationwide. The bus drivers in that town drive as if they own the road and are ready to pounce on anyone who dears them. I wish some of you will visit that town with your car and drive just for a month then you will think twice before making some rash comments. For the record, I am not a traffic officer but am saying this because I have lived in that town and encountered them also. No one has the right to take the life of the other.

love letters have started dropping. Thank you NLNG for the opportunity to apply and write SHL test. we move.......

so gradually the process is ongoing. Those who wrote the first batch, have they been called for interview or it will be together?

@Nicer, Please any idea on when interview mails for EH will drop?

Please guys when are they sending mail for interview?

So have they really started calling EH for interview?

CONGRATULATIONS ARE IN ORDER. WELDONE

SCAM SCAM SCAM. RUN VERY FAR

Just got the mail.
Please how can we get shl materials for this test?

hey all of speaking without reason. d girl is cool and simple why can't u guys learn to appreciate our own? to me she is just cool and good..

I ALSO GOT THE MAIL FROM NOVOTEL AND WAS ASKED TO CONTACT THEIR TRAVEL AGENCY 'ADS TRAVEL AGENCY', AND WAS ALSO SENT AN EMPLOYMENT/CONTRACT TERMS OF AGREEMENT. WHAT MADE ME LOOKED AT IT TWICE WAS THE PHONE AND FAX NUMBERS THERE WHICH ARE QUITE DIFFERENT FROM THE ACTUAL NOVOTEL. THAT IS TO SAY THAT TRAVEL AGENCY THAT DOES NOT EXIST IS THEIR WAY OR MEANS OF MAKING MONEY FROM INNOCENT AND UNSUSPECTING NIGERIANS, THESE SCAMMERS WILL THEY EVER STOP? PEOPLE SHOULD SHINE THEIR EYES IN EMPLOYMENT MATTERS AND THOSE INVOLVED SHOULD BE CAUGHT AND BROUGHT TO BOOK.

THERMODYNAMICS QUESTIONS

1. FIG 1 below shows a combined Gas- steam cycle featuring two gas turbines T1 and T2 and a steam turbine T3. These turbines drive the compressor A and the electric generator G1 and G2. The compressor is of pressure ratio ɤpc adiabatic efficiencies of the compressor, the turbines and the pump are ηc, ηT1, ηT2 and ηp respectively. Numerical data are tabulated here under:
T1a T3a T5a T2b P2b P3b ɤPC ηC ηT1 ηT2 ηP
295 1200 440 500 30 10 6 82 85 82 78
---- (K) - - - - - - (C) (bar)- - - - - - - - - (%) - - - --
What would be (i) the mass flow rate ratio of air and steam (ṁa/ṁs), and (ii) the overall thermal efficiencies (ηth) of the combined cycle.

2. FIG 2 depicts possible application of the Brayton cycle for automotive propulsion.
Two adiabatic turbines C and D of efficiency ηT are employed, turbine C devoted to the
Compressor A (adiabaically) and turbine D, the power turbine for driving the drive
Wheels, interposed between the turbines is a throttle valve V. The compressor of
Efficiency ηC feeds the burner B (essentially a constant-pressure heat exchanger) which
Is supplied with fuel, the mass flow rate is negligible compared with the air (ideal gas of
Constant Cv and R). Two scenarios (I and II) are envisaged, the former being the full load
(wide-open throttle situation with P4= P5), and the latter the no- load (with partially
Open throttle situation and P5=P6). For each of the two scenarios,
(i) Draw the TS diagram and evaluate
(ii) P5, T5, P6, T6
(iii) The specific work output of the turbines
(iv) The energy conversion efficiency (scenario I only)
(v) Given Qcv as the calorific value of the fuel, what specific fuel consumption
(kg/KWh) occurs in scenario I?
(vi) The specific heat transfer in the burner
(vii) What air flow rate would be called for to support a particular power output Wdo.
Data are displayed:

if this man saying this rubbish has ever lost a dear one in the kind of misnomer that happened b4 in Bauchi, i dont think he will open his dirty mouth of a gutter to talk. if GEJ is wise he should do away with ministers of this nature.

guys dis is a very sensitive case dat requires deep thinking rather than jumping into unholy conclusions or believing no one can read it better and understand. the case continues, lets watch how they play it out.God help us all

GUYS THE POLYTECHNIC IS MEANT TO PRODUCE MIDDLE LEVEL MANPOWER, AT THAT LEVEL IT IS THE B.Sc MAN THAT SUPERVISES. THERE IS DIFFERENCE BETWEEN THE UNIVERSITY AND THE POLYTECHNIC SO PEOPLE SHOULD GET THE RIGHT ORIENTATION BEFORE GETTING ONE OVER THE OTHER. U AV A CHOICE IN SPITE OF THE SITUATION.

for the govt to tell u that u will suffer for ur children to enjoy, wat do u expect? delay of salary, kill the poor pple and their children, reduce population etc. dats the formula, bad govt we have no palliatives cos subsidy is not removed 100%.

whether or not, the truth is that previous administrations have been precarious and have taken the entire Nigerians to be a conglomeration of hounds. GEJ, NOI and the rest are only replicating wat we av been seeing and ignoring, but I think the time will soon be right wen we will take our destinies in our hand and there will be serious revolution in this country that will purge the leaders out. lets all be aware, it will soon come.
