Regarding the definition of exhaust volume, which of the following description is correct?
A. The actual volume of compressed gas output by the air compressor per unit time
B. Gas discharge capacity after taking into account efficiency losses
C. Theoretical value of the geometric volume swept by the piston per unit time
D. Value that needs to be converted to standard state
Answer: C
parsing: The displacement is the theoretical design value, which refers to the geometric volume swept by the piston or screw rotor per unit time, regardless of actual loss.
