In a piston cylinder system, a fluid at 0.8 bar occupying 0.07 m³ is compressed reversibly to a pressure of 10.2 bar and specific volume of 0.6 m³/kg C. according to the law pv = c. The fluid then expands reversibly according to the law pv² = c to 1.1 bar. A reversible cooling at constant volume then restores the fluid back to initial state. Calculate the net work for the process in Joules. To 3 d.p. and insert the unit symbol joules.

Question
In a piston cylinder system, a
fluid at 0.8 bar occupying 0.07
m³ is compressed reversibly to
a pressure of 10.2 bar and
specific volume of 0.6 m³/kg
according to the law p = c.
The fluid then expands
reversibly according to the law
pv² = c to 1.1 bar. A reversible
cooling at constant volume then
restores the fluid back to initial
state. Calculate the net work for
the process in Joules.
To 3 d.p. and insert the unit
symbol joules.
