Q15
Volumetric efficiency of a compressor without clearance volume
A.
Increases with increase in compression ratio
B.
Decreases with increase in compression ratio
C.
Is not dependent upon compression ratio
AnswerD.
May increase/decrease depending on compressor capacity
Answer: Option C
Solution
Answer: Option C
Solution:
A compressor's volumetric efficiency (V) is defined by the ratio of the actual volume of gas that it could suck if there was no such thing as clearance volume. Therefore, a compressor with less clearance volume should be more volumetrically efficient.
