In an ideal Rankine cycle, as shown below, saturated water vapor enters the turbine at 20 MPa and exits at 10 kPa. Saturated liquid exits the condenser. Determine the following characteristics of the power cycle:

A. The net work per unit mass of steam flow (kJ/kg)

B. Heat input per unit mass of steam flow (kJ/kg)

C. The overall cycle thermal efficiency

D. The heat rejection per unit mass of steam flow (kJ/kg)
