Please could you explain to me how to solve this exercise Consider a modified cogeneration power plant with regeneration. Steam enters the turbine at 6MPa and 450ºC at a rate of 20Kg/s, and expands to a pressure of 0.4MPa. At this pressure 60% of the water vapour is extracted from the turbine, and the rest is expanded to a pressure of 10KPa. Part of the extracted steam is used to heat the feed water in an open feed water heater. The rest of the extracted vapour is used for process heating, and leaves the process heater as a saturated liquid at 0.4MPa. It is then mixed with the feed water leaving the feed water heater, and the mixture is pumped to boiler pressure. The vapour in the condenser is cooled and condensed by cooling water from a nearby river, which enters the adiabatic condenser at a rate of 463Kg/s. Consider the ideal equipment and demonstrate the enthalpy values shown a) The temperature rise of the river cooling water in the condenser is: (R=8°C) b) The mass flow of steam…
A 600-MWe power plant has an efficiency of 36 % with 15% of the waste heat beingreleased to the atmosphere as stack heat and the other 85% taken away in the coolingwater. Instead of drawing water from a river, heating it, and returning it to the river, this plant uses an evaporative cooling tower wherein heat is released to the atmosphere as cooling water is vaporized. At what rate must 15 °C makeup water be provided from the river to offset the water lost in the cooling tower?
Consider a steam power plant that operates on a simple ideal Rankine cycle and has a net power output of 20MW. Steam enters the turbine at 7MPa and 450.210C and is cooled in the condenser at a pressure of 10kPa by running cooling water from a lake through the tubes of the condenser at a rate of 1750kg/s. Determine the value of enthalpy of steam at the entry to the steam turbine (accurate to 4 decimal places, using the relevant equations) assuming that the cp of superheated steam is 2.9699kJ/kg.K.
Steam enters the high-pressure turbine of a steam power plant that operates on the reheat Rankine cycle at 10 MPa and 600°C and leaves at 4 MPa. Steam is then reheated to 500°C before it expands to a pressure of 30 kPa. The enthalpy of steam is 3330 kJ/kg at the exit of the high-pressure turbine, and 2600 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, the cycle efficiency is
A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at 10°C by rejecting waste heat to cooling water that enters the condenser at 18°C at a rate of 0.25 kg/s and leaves at 26°C. The refrigerant enters the condenser at 1.2 MPa and 50°C and leaves at the same pressure subcooled by 5°C. If the compressor consumes 2.3 kW of power, determine the COP?

Steam generated at a power plant at 8.0 MPa and 600.°C is fed to a turbine. Exhaust from the turbine enters a condenser at 25 kPa where it is condensed to a saturated liquid, which is then pumped to the boiler. What is the thermal efficiency of a Rankine cycle with a reversible adiabatic turbine operating at these conditions?
A gas-turbine power plant operates on a simple Brayton cycle with air as the working fluid. The air enters the turbine at 120 psia and 2000 R and leaves at 15 psia and 1200 R. Heat is rejected to the surroundings at a rate of 6400 Btu/s, and air flows through the cycle at a rate of 40 lbm/s. Assuming the turbine to be isentropic and the compressor to have an isentropic efficiency of 80 percent, determine the net power output of the plant. Account for the variation of specific heats with temperature.
