Q2: Consider a steam power plant that operates on a simple Rankine cycle and has a net power output of 45 MW. Steam enters the turbine at 7 MPa and 500°C and is cooled in the condenser at a pressure of 10 kPa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. assuming an isentropic efficiency of 87 percent for both the turbine and the pump. Show the cycle on a T-s diagram with respect to saturation lines, and determine (a) the thermal efficiency of the cycle, (b) the mass flow rate of the steam, and (c) the temperature rise of the cooling water.

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?

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…
