A piston-cylinder device contains 0.60 kg of water initially at 300 kPa and the quality is 0.60. The water is first expanded at constant pressure to 300 ^oC and then compressed isothermally to saturated vapor. It is finally compressed poly tropically with a polytropic exponent of 0.20 to the initial state. Determine: 

a) The boundary work for each process 

b) The network of the cycle.
