In axial flow compressor, exit flow angle deviation from the blade angle is a function of
blade camber
blade camber and incidence angle
space-chord ratio
blade camber and space-chord ratio
✅ The correct answer is option B.
The volume of air delivered by the compressor is called
free air delivery
compressor capacity
swept volume
none of these
✅ The correct answer is option B.
Intercooling in compressors results in saving of power in compressing given volume of air to a given pressure.
Correct
Incorrect
✅ The correct answer is option A.
A large clearance Volume in a reciprocating compressor results in
reduced volume flow rate
increased volume flow rate
lower suction pressure
lower delivery pressure
