Question

Air that initially occupies 0.28 m³ at a gauge pressure of 56 kPa is expanded isothermally to a pressure of 101.3 kPa and then cooled at constant pressure until it reaches its initial volume. Compute the work done by the air. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.)

Step 1

The atmospheric pressure is $P_{atm} = 101.3 \, kPa$. The initial actual pressure is $P_1 = P_{g1} + P_{atm} = 56 + 101.3 = 157.3 \, kPa$. The initial volume is $V_1 = 0.28 \, m^3$. Show more…
