(B) absolute discharge pressure to the ab-solute intake pressure (
)
(C) pressures at discharge and suction cor-responding to same temperature (X)
(D) stroke volume and clearance volume (X)
(E) none of the above (X)
Answers: Ratio of compression is the ratio of absolute discharge pressure to the ab-solute intake pressure.
