Regenerative Cycle (Open Feedwater Heater): 4. Steam enters the turbine at 10 MPa and 550 °C with mass flow rate of 10 kg/s and is condensed in the condenser at a pressure of 10 KPa. Some Steam is extracted from the turbine at 0.8 MPa and enters in an open feedwater heater. Determine the amount of steam that is condensed in the condenser.5. 23 percent of the steam is extracted from the turbine. The enthalpy and pressure at point 6 is 3100 KJ/KG and 1.26 MPa respectively. Determine the enthalpy of point 2.6.

A steam Rankine cycle operates with a condenser temperature of 30°C, and a boiler pressure of 15MPa. The turbine is divided into two stages, a high-pressure turbine, and a low pressure turbine. In between the turbine stages the steam is reheated by the boiler so that the inlet temperature to both turbine stages is the same. The exit pressure of the first turbine stage is 7MPa. The condenser inlet is a saturated vapor and the outlet a saturated liquid. What is the net work of the cycle? What is the thermal efficiency of the cycle?
Water is the working fluid in a Rankine cycle. Superheated vapor enters the turbine at 8 MPa, 5608C with a mass flow rate of 7.8 kg/s and exits at 8 kPa. Saturated liquid enters the pump at 8 kPa. The isentropic turbine efficiency is 88%, and the isentropic pump efficiency is 82%. Cooling water enters the condenser at 188C and exits at 368C with no significant change in pressure. Determine: (a) the net power developed, in kW. (b) the thermal efficiency. (c) the mass flow rate of cooling water, in kg/s
Superheated steam from the boiler expands in the turbine from inlet pressure p₁ of 50 bar and temperature 7 of 487 °C to condenser pressure p2 of 18 kPa. In the condenser, the steam condenses to saturated water. The isentropic efficiency of the turbine ns is 78.0 %. The mass flow of steam 9m,h is 140 kg/s. In the boiler, heat flow rate to the circulating fluid (water/steam) is 458 MW. Read from h,s-diagram and calculate: 1. Enthalpy of the superheated steam h kJ/kg (with zero decimal accuracy) 2.
