PROBLEM 2A steam engine consisted of a large boiler used to heat H2O up 1600°C at a certain time. During a normal operational stage, the boiler is capable of transfering heat effectively to a turbine at a rate of 4000 kJ/s with an average surrounding temperature of 30°C.a) Assuming that this is reversible device, calculate the thermal efficiencyb) Calculate the rate of exergy flow that is resulted from the heat transfer. c) If the power output produced from the steam turbine is 100 kJ/s, calculate the irreversibility rate for this process.
