Question

M Example 3.5 A piston and cylinder machine containing a fluid system
has a stirring device in the cylinder (Fig. 3.22). The piston is frictionless,
and it is held down against the fluid due to the atmospheric pressure of
101.325 kPa. The stirring device is turned 10,000 revolutions with an
average torque against the fluid of 1.275 mN. Meanwhile the piston of
0.6 m diameter moves out 0.8 m. Find the net work transfer for the system.
