HW-33 (25 points) Superheated steam at an absolute pressure of 20 MPa and a temperature of 560°C flows into the turbine of a Rankine cycle. The absolute pressure at the turbines outlet is 0.5 bar, and liquid exits the condenser at an absolute pressure of 0.4 bar and a temperature 75°C. The absolute pressure is increased to 20.1 MPa across the pump. The turbine and pump have isentropic efficiencies of 81% and 85%, respectively. Cooling water enters the condenser at...

Fuel is burned in a boiler to produce saturated steam at 10.0 bar absolute pressure from saturated liquid water at 10.0 bar absolute pressure. This H20 flows through tubes that run through the boiler, Energy released by combustion is transferred as heat through the walls of the tubes to convert the liquid water to steam at 10.0 bar. The fuel consists of 37 mol% ethane and 63 mol% acetylene, and is fed in the vapor phase at 50 °C 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...
