PE Mechanical Thermal Fluids

Practice session

A simple ideal Rankine cycle has boiler pressure 8 MPa and condenser pressure 10 kPa. Steam leaves the boiler superheated with h3 = 3399 kJ/kg. After isentropic expansion h4 = 2200 kJ/kg, and pump work raises h1 to 200 kJ/kg from h2 = 192 kJ/kg (saturated liquid at 10 kPa). What is the cycle thermal efficiency?
