Steam enters an adiabatic turbine steadily at 7 MPa, 500 °C, and 45 m/s
Steam enters an adiabatic turbine steadily at 7 MPa, 500 °C, and 45 m/s, and leaves at 100 kPa and 75 m/s. If the power output of the turbine is 5 MW and the isentropic efficiency is 77 percent, determine: A. the mass flow rate of steam through the turbine, B. the temperature at the turbine exit, and C. the rate of entropy generation during this process.

In a steam power plant, water is pressurized in an adiabatic pump from 100kPa as a saturated liquid to 5 MPa at 150C. The pump is directly driven by an adiabatic steam turbine, which also powers a generator. Steam enters the steam turbine at 5 MPa and 450C and leaves as saturated vapor at 100kPa. Determine the net-work output of the pump-turbine-generator combination if the generator operates at 85% efficiency. (in kJ/kg) ) b) Determine the entropy generation for both...

01: Steam enters the first turbine at 15.0 MPa and 600°C. The pressure in the condenser is 20.0 kPa. While some steam is extracted from the high-pressure turbine at 5 MPa and sent to the closed feedwater heater, the remaining steam is reheated to 600°C. The extracted steam is condensed as saturated liquid at 5.0 MPa and trapped to the open feedwater heater. Some steam is extracted from the lower-pressure turbine at 1.0 MPa and sent to the open feedwater...

#4. To operate a steam turbine in part-load output, a throttling valve is used as shown. The valve reduces the pressure of steam before it enters the turbine. The state of steam in the supply line remains fixed at 2 MPa, 500°C and the turbine exhaust pressure remains fixed at 10 kPa. Assuming the turbine to be adiabatic and reversible, determine (a)the full load specific work output in kJ/kg, (b)the pressure of the steam must be throttled to for 75%...

Ctri Alt Part B (80 points) A nuclear reactor power plant utilizing water as the working fluid is to be analyzed in this problem. The reactor vessel (like a boiler) receives water from a pump and with heat addition produces water at 1500 lbf/in.2 and 500 F. The high-temperature compressed liquid from the reactor is throttled (in a valve) into a flash evaporator separating the fluid into vapor (saturated) and liquid at 300 lbf/in.2. The fraction of the water that...
