Consider a steam power plant that operates on a simple, ideal 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. Show the cycle on a T-s diagram with respect to saturation lines, and determine The thermal efficiency of the cycle,The mass flow rate of the steam and the temperature rise of the cooling water
Two reversible heat engines operate in series between a source at 600°C, and a sink at 30°C. If the engines have equal efficiencies and the first rejects 400 kJ to the second, calculate: the temperature at which heat is supplied to the second engine, The heat taken from the source; and The work done by each engine.
Assume each engine operates on the Carnot cycle

- A steam turbine operates at steady state with inlet conditions of P1 = 5 bar, T1 = 320°C. Steam leaves the turbine at a pressure of 1 bar.
