Consider a power plant operating on the ideal Rankine cycle with R134A as a medium. The turbine is operated at 1.4 MPa and the condenser works at 100 kPa. The mixture at the exit of the turbine has a quality of 98.53% 1. Determine the work-input of pump. 2. Determine the heat addition in the boiler.
A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 3 psia in the condenser. The turbine inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kW of power. How much error is caused in the thermal efficiency if the power required by the pump were completely neglected? Use steam tables. The error caused in the thermal efficiency if the power required by the pump was completely neglected is %.
Biomass is used as fuel to power the following cogeneration plant on a school. The turbine drives an electric generator to produce electricity, and part of the steam is extracted to provide heating to campus buildings. The boiler provides 106 kg/h of steam at 6 MPa, 520 °C, of which 4x105 kg/h is extracted between the first and second turbine stages at 1 MPa and diverted to the building heating load. Condensate returns from the building heating load at 0.95 MPa, 115 °C, and it is mixed with liquid exiting the lower pressure pump at 0.95 MPa. The entire flow is then pumped to the boiler pressure. Saturated liquid at 6 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 89 and 85%, respectively. The efficiency of the electric generator is 93% for converting turbine mechanical power into electricity. Calculate the heating load in kJ/h. Calculate the electric power generated in MWe.
An ideal RANKINE cycle delivers 210 MW of power. Steam enters the turbine at 10 MPa and500C and is cooled in a condenser at 10 kPaa. Determine the thermal efficiency of this cycleb. Mass flow of waterc. Heat rejected in the condenserd. Work inputted to the pump (remember the volume is constant)

May you please be as detailled as possible. Thank you
A flashed steam geothermal power plant is located where underground hot water is available as a saturated liquid at 700 kPa. The well-head pressure is 600 kPa. The flashed steam enters the steam turbine at 500 kPa and expands to 15 kPa when it is condensed. The flow rate from the well is 29.6 kg/s. Determine the cycle thermal efficiency of the plant in %. If the steam table is needed, please use the green book entitled "Thermodynamics Properties of Water Including Vapor, Liquid, and Solid Phases" by Keenan, Keyes, Hill, and Moore.
Hi, I need help with this practice problem for Thermodynamics
Oren is hired to design a massive 450 MW power plant for the city of Dubai. Oren decides that the optimal efficiency would be obtained if the pressure of saturdted vapár entering the turbine should be 10 MPa.and the presJure of saturated liquid exiting the condensor to be 0.005 MPa. Dubai is in the United Arab Emirates (UAE), where the water from the Persian Gulf is 4O °C and UAE environmental laws limit the exiting coa ling water to a maximum temperature of 45°C (to prevent damage to local fishing industry). For Oren's power plant, calculate : A.) heat input from the boiler (in MegaWatts) B.) thermal efficiency C.) mass flow rate of caoling water (in k/s)
