Q43: In the schematic shown below, what will happen, if the flow through the following constant speed reciprocating compressor reduces: 

Which one of the following will you agree with:

 

A.  Suction pressure increases

B.  Discharge temperature increases

C.  Suction pressure reduces

D.  Discharge temperature reduces

 

B & C; For gas system, flow is proportional to the pressure and so, reduction in flow would correspond to reduction in pressure. For reduced flow, with same power, gas will be compressed more resulting in a higher discharge temperature.

Q44. Guess the six letter word.
The first four letters mean me.
The second and last letters are the same.
The fourth, second and last letters together mean payment.

 

Selfie
Selfie  = is six letter word.
Self    = The first four letter mean me.
e         = The second and last letter are the same.
fee     = The fourth, second and last letter mean payment.
