400 kW
Option (C)
800 kW
Option (D)
1600 kW
Correct Option:
B
Question:-
Option (A)
an increase in velocity and decrease in pressure
Option (B)
a decrease in velocity and increase in pressure
Option (C)
a decrease in velocity and pressure
Option (D)
an increase in velocity and pressure
Correct Option:
A
Question:-
Option (A)
Steam separator
Option (B)
Steam trap
Option (C)
Pressure reducing valve
Option (D)

Correct Option:
B
Question:-
Option (A)
248 cc
Option (B)
252 cc
Option (C)
264 cc
Option (D)
286 cc
Correct Option:
C
Question Solution:
Volumetric efficiency is the ration of the actual mass of air induced by the engine on the intakes stroke to the theoretical mass of air that should have been induced by filling the piston-displacement volume with air at atmosphere temperature and pressure volume of mixture taken = 300 x 0.88 = 264cc
Question:-
Option (A)
Reduced volume flow rate
Option (B)
Increased volume flown rate
Option (C)
lower suction pressure
Option (D)
Lower delivery pressure
Correct Option:
A
Question Solution:
The clearance volume is the space between piston top and inner surface of the cylinder head. The clearance volume reduces the capacity of the compressor and volume flow rate
