A combined gas-steam power plant uses a simple gas turbine for
the topping cycle and a simple Rankine cycle for the bottoming
cycle. Atmospheric air enters the compressor at 101 kPa and 20 °C,
and the maximum gas cycle temperature is 1100 °C. The
compressor pressure ratio is 8. The gas stream leaves the heat
exchanger at the saturation temperature of the steam flowing
through the heat exchanger. Steam enters the heat exchanger at a
pressure of 6 MPa and...

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...

Problem 3 Steam enters a heat exchanger at 0.1 bar with a quality of 0.95 and condensate exits at 0.1 bar and 45'C. Cooling water enters the heat exchanger in a separate stream as a liquid at 20'C and exits as a liquid at 35 C with no changes in pressure. Heat transfer from the outside of the heat exchanger and changes in the kinetic and potential energies of the flowing streams can be ignored. For steady state operation, (a)...

Steam is to be condensed by direct injection of cold water. Steam enters the condenser at a rate of 450 kg/h with a quality of 0.90 and a pressure of 1 atm. The estimated heat loss from the condenser to the surroundings is 8500 kJ/h. If the cold water enters with a temperature of 15°C and the mixture leaves at 95°c, determine the rate of cooling water required. 3. Φ 2-phase Steam . 9 3 -95c 2 Cold Note

Superheated steam at 20 MPa, 560oC enters the turbine of a vapor power plant. The pressure at the exit of the turbine is 0.7 bar, and liquid leaves the condenser at 0.4 bar at 75oC. The pressure is increased to 20.1 MPa across the pump and the specific enthalpy is 338.14 kJ/kg. The turbine isentropic efficiency is 81%. Cooling water enters the condenser at 20oC with a mass flow rate of 70.7 kg/s and exits the condenser at 38oC. For...

A steam power plant operates on the reheat Rankine cycle. Steam enters the high-pressure turbine at 12.5 MPa and 5508C at a rate of 7.7 kg/s and leaves at 2 MPa. Steam is then reheated at constant pressure to 400 C before it expands in the low-pressure turbine. Steam leaves the condenser as a saturated liquid. The exit of the turbine is saturated at the condenser pressure (a) the condenser pressure, (b) the net power output, and (c) the thermal...
