It is so appauling that this thread which is supposed to be educating and enlightening as we prepare for the intervew has been taken over by immaturity and infantry. From dwelling so much on grammatical blunders, to value-eroding discussions, and insults. No one is talking about likely interview questions. No one is looking out for a fellow who share their major to discuss field-specific questions that may arise during the interview. You all should take a cue from the NLNG thread. Before you make a post, you should ask yourself if an HR rep from NNPC would consider you employable after reading such. Please let's make this thread meaningful again.

Mechanical engineering GT hopefuls, how is your prep? I am expecting questions from thermodynamics, int comb engines, Eng design, strength of materials, turbo-machinery and fluid mechanics. What's your take?

My broda the questions may not be that technical, maybe 1 or 2 though. Be rest assured that it will be CV based and it will proceed in line with the direction of your answers.

For instance:
Q: Which subsidiary would you like to work in and why?

Q: You said you prefer to work in IDSL. Tell us how you would explain to an uncle in the village, the importance of IDSL?

Q: You studied Agric. Econs. Can u tell us how renewable energy can affect the agricultural sector; the opportunities and the likely challenges.

One funny one could be: as you walk in and have finished greeting the panel. One of them may just ask u with a stone cold look, ''What are u doing here?!'' loool. This one is sure to throw some ppl off balance.

KINGTELLER:

Men !! that fluid mechanics is something I might have forgotten oo... Hope they wont ask one one to start deriving formulars on viscous flow in pipes under shear stress and pressure?

This interesting, I have been looking for mech eng guys, not forgeting rotating equipments as well.
There are some questions I have been ask in several interview as a mechanical engineer, let's share it here. The questions are
What is the different between 4 stroke and 2 stroke engine?
What is the firing order of a 4 cylinder engine?
What are the laws of Thermodynamics.

No comment is wrong, let's share idears mech engineers

hmm Babacha,wit dis ur aboki name,u r one of doz fightin western education...abeg i no get dat time to correct all doz ur many errors...shey u cn see nw,wen ur mates whr inside english class,u whr ontop mango tree,pluckin mango 2eat...dnt quote me again,if nt we wud ask u to produce ur original certificate

KINGTELLER:

Four stroke engine performs 4 cycle process of gas (Intake, Compression, combustion and exhaust)
The firing order of 4 cyclinder engine adopts the 4 cycles process though applying carnot cycle process to reducess energy loss by adiabatic process

What is the total capacity in barrel(bbl) of a rectangular tank 5 meters in height knowing that it will hold 200 leters per foot?

Guy I be full delta guy o, and I be mech eng to the core and I can defend it to any level, not just the theory but the practical. Mech eng flows in my blood, is like a food I eat every day cos my work every two weeks in a month revolve around it. Especially diesel engine and rotating equipments

lobito007:

Nice one bro. 2-stroke engines do not have valves and fire once every revolution, unlike 4-stroke engines which fire once every two revolutions.
Firing order of a 4-cylinder engine: varies depending on the type of engine. However, most engines now run on 1-3-4-2

KINGTELLER:

Solution:
1 Litre per foot= 304.8m
200 Lpf (200×304.8 ) = 60960m
60960×5 (H of rect) = 304800m cubic
since 1bbl = 0.158m cubic
304800/0.158= 1929112 bbl

lobito007:
Here's a question I was asked at an interview: Why is diesel engine preferred to petrol engine in heavy-duty vehicles?

KINGTELLER:

So u be Delta, ehen naa u I go dey compete slot with abi... Make I go jack more studies... which side of delta are u from

This thread is taking a boring dimension.

KINGTELLER:


Modify:
1Lpf = 0.00328 m sq ................ conver 1
1bbl = 0.119 cubic meter...........conver 2

from conver 1, get the conversion of of the 200Lpf and multiply by height to get volumetric

200 × 0.00328=0.656m sq
0.656×5 (Height of rect) =3.28 cubic m

Divide the cubic meter with convers 2 to get the no. of barrel

3.28/0.119= 27.56 barrel (bbl)

babacha:


Still not correct, liter is volume so coverting it to m sq is not correct, u only convert liter to meter cub.
Try convert the 5m to ft so that u get u total volume in liters before u covert to bbl to make it easy

uyosolo:

dats gud,am a welding engr 4rm pti,so i knw alot abt delta ppl...i tot u were a mallam b4

KINGTELLER:





Then your question is faulty, (see bolded) check google for litre per foot conversion, its equivalent to meter sq on conversion scale

http://www.google.com.ng/search?hl=en&ie=ISO-8859-1&q=what+is+litre+per+foot

babacha:


This question I give is in schlumbeger past question

From conversion,
5m equal to 16.4ft
From the question,
U have 200liters in every 1 ft
Therefore,
U have 3280 liters in 16.4ft
That is 200*16.4 that is the volume in leiters,
From conversion again
3.785liters equal to 1gallon
So 3280liters equal 867gallons
From conversion again
1bbl equal to 42gallons
So 867gallons equal 20.6 or 21bbl
Final answer

SomBaby:

Its alright...you are welcome...
Thank you for the compliment

lobito007:

Interesting. Thanks for the insight. Obviously you were an interviewee. Did you make the cut?
