Air is compressed in an insulated cylinder from 47ºC and 120 kPa to 1200 kPa. Assuming negligible losses, the final temperature of this isentropic process is nearest:
A) 337ºC
B) 492ºC
C) 561ºC
D) 610ºC
A) 337ºC
The reduced pressure at state 2 is found,
The temperature that possesses this Pr2 is interpolated to be close to 610 K or 337ºC.
