Question 2.17: A piston and cylinder machine containing a fluid system has ...

Engineering Thermodynamics

A piston and cylinder machine containing a fluid system has a stirring device as shown in Fig. 2.36. The piston is frictionless, and it is held down against the fluid due to atmospheric pressure of 101.3 kPa. The stirring device is turned 9500 revolutions with an average torque against the fluid of 1.25 Nm. Meanwhile the piston of 0.65 m diameter moves out 0.6 m. Find the net work transfer for the system.
