Question 1 (a) KD Plantation operates a 150 MW vapor power cycle with a steam turbine that can only withhold a maximum pressure of 10 MPa. The turbine's isentropic efficiency is 0.80, whereas the pump's efficiency depends on pump = 0.80-(1- Xout) x 0.5. Given that the average temperature at KD is 30°C, determine all the state properties, the mass flow rate and the thermal efficiency of the cycle. Propose a change in the cycle design to increase the thermal efficiency by at least 12%.
