Hello I was asked a question on a mock exam paper,and I am unsure of the correct answer.
The question was Capacity control of a screw compressor is generally accomplished by:
(a) Hot gas bypass
(b) throttling the suction vapour
(c) Cylinder unloading
(d) sliding valve
I did not get this correct,and i am unsure still.
I think it might be (a) though.
