Water is the working fluid in a vapor power plant. Superheated steam leaves the steam generator at 8.2 MPa, 540 °C and enters the turbine at 7.5 MPa, 500 °C. The steam expands through the turbine, exiting at 8kPa with a quality of 94%. Condensate leaves the condenser at 5 kPa, 30 °C and is pumped to 9 MPa before entering the steam generator. The pump efficiency is 80%. Determine (a) the thermal efficiency of the cycle and (b) the net power developed.

A power plant operating in a Reheat Rankine Cycle produces steam at 3 MPa, 600oC in the boiler. It keeps the condenser at 45oC by transfer of 10 MW out as heat transfer. The first turbine section (high-pressure) expands to 500 kPa and then flow is reheated followed by the expansion in the low-pressure turbine. Provide a detailed solution. Avoid shortcuts. Find the boiler heat transfer including the reheat process (kW)
Q2. A cogeneration steam power plant has been modified with introducing an open feedwater heater as shown in figure below. Working pressure of the plant is between 6 MPa and 10 kPa for the boiler pressure and condensate pressure. The steam is extracted at 0.5 MPa for process heater and feedwater heater. The superheated srteam enters the turbine at 500°C at a rate of 25 kg/s and expands to the condensate pressure of 0.5 MPa. There is 60 percent of the steam is extracted from the turbine at the pressure of 0.5 MPa, and the remainder expands to a pressure of 10 kPa. Part of the extracted steam is used to heat feedwater and the rest of the extracted steam is used for process heating. The steam leaves the process heater as a saturated liquid at 0.5 MPa. It is subsequently mixed with the feedwater leaving the feedwater heater, and the mixture is pumped to the boiler pressure. The steam in the condenser is cooled and condensed by the cooling water from a nearby river, which enters the…

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 %.

Hi, I need help with this practice problem for Thermodynamics
A binary-vapour cycle operates on mercury and steam. Saturated mercury vapour at 4.5 bar is suppliedto the mercury turbine, from which it exhaust at 0.04 bar. The mercury condenser generates saturatedsteam at 15 bar which is expanded in a steam turbine to 0.04 bar.(i) Find the overall efficiency of the cycle.(ii) If 50000 kg/h of steam flows through the steam turbine, what is the flow through the mercuryturbine ?(iii) Assuming that all processes are reversible, what is the useful work done in the binary vapour cyclefor the specified steam flow ?(iv) If the steam leaving the mercury condenser is superheated to a temperature of 300°C in a superheaterlocated in the mercury boiler, and if the internal efficiencies of the mercury and steam turbinesare 0.85 and 0.87 respectively, calculate the overall efficiency of the cycle. The properties ofsaturatedmercury are given below :
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)
