Question: An Actual Steam Power Plant Operates On A Conventional Rankine Cycle... An actual steam power plant operates on a conventional Rankine cycle with the following data: Pump inlet and exit pressures are 9kPa and 16.2 MPa, respectively; Pump inlet and exit temperatures are 38°C and 35 °C ; isentropic pump efficiency is 0.86. Note that this is an actual plant and thus, temperature may drop due to heat loss in the piping between the pump and the boiler. • Boiler inlet pressure and temperature are 16 MPa, and 36°C, respectively; Boiler exit pressure and temperature are 15.2 MPa and 630°C, respectively. • Turbine inlet pressure and temperature are 15 MPa and 605 °C, respectively; Turbine exit pressure is 11 kPa; Isentropic Turbine efficiency is 0.9. a. Draw the plant schematic diagram showing the components and mark the temperature and pressure values at different points along the path. b. Draw the Rankine Cycle on T-S diagram c. Calculate the thermal efficiency of the cycle d. Calculate the plant net power output for a mass flow rate of 20 kg/s e. For the Steam power plant described in Problem 1, list all possible techniques that can be implemented to increase the thermal efficiency of the plant. Briefly
