Asteam power plant operates on the rankine cycle with steam en rankine cycle with steam entering the high pressure turbine at 80 bar, 560°c with a mass flow rate of 2x10 kg/hr. the flow rate of 2x100kg/hr. the steam exits the high pressure turbine at 5 bar, 180°c where the steam is then sent back where the steam is then sent back to the boiler and reheated to 480°c before expanding through the low pressure turbine to cooling water enters the condenser from a lake at 20°c and exits at 32°c. assume the low pressure turbine has an isentropic efficiency of 92% and that the pumps opera isentropically. draw a t-s diagram of this cycle and determine the following: high pressure turbine isentropic efficiency net power output, mw low pressure turbine exit quality cycle thermal efficiency the mass flow rate of the cooling water from the lake
