a)Show the P-v diagram, taking into account the process change saturation curves.

b)Find the work done during the process

c)Find the heat transferred during the process

A liquid-vapor (2 phase) mixture of water, initially with a quality of 30% and a pressure
of 100 kPa, is contained in a piston-cylinder assembly as shown below. The mass of the
piston is 10 kg, and its diameter is 15 cm. The pressure of the surroundings is 100 kPa.
As the water is heated, the pressure inside the cylinder remains constant until the piston
hits the stops. Heat transfer to the water continues at constant volume until the pressure
is 150 kPa. Friction between the piston and the cylinder wall can be neglected, as can PE
and KE. For the overall process of the water, determine the work and heat transfer, each
in kJ. (0.106, 1.43)
