2. A geothermal power plant is supplied with water at 260°C and a pressure of 10 MPa. The fluid flows to a flash unit, exiting as liquid and vapor streams at 0.5 bar. Vapor from the flash unit is fed to a turbine. The turbine exit pressure is 0.02 bar. The overall turbine efficiency is 0.83. Calculate the thermal efficiency, the heat rate, and steam and water mass flow rates required for an output of 5 MW.

Can someone help, please?

A power plant operates on a regenerative vapor power cycle with one open feedwater heater. Steam enters the first turbine stage at 12 MPa, 560°C and expands to 1 MPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 17 kPa. Saturated liquid exits the open feedwater heater at 1 MPa. The net power output for the...

QUESTION 5 A steam power plant is designed to operate on a reheat Rankine cycle to produce 115 MW of a net power output. Due to metallurgical limitation, the high-pressure turbine is limited to operate at maximum pressure and temperature of 15 MPa and 650°C, respectively. The lowpressure turbine is to operate at maximum pressure and temperature of 3.5 MPa, and 500°C, respectively. Both high and low pressure turbines have maximum isentropic efficiency of 87 percent. The maximum reheat pressure...
