4. A steam plant operates on a thermodynamic cycle based on two isobaric processes and two isentropic processes. Pure water enters the plant at a rate of 10 kg slat 80 bar and the saturation temperature. It is isobarically heated to 550 C and then isentropically expanded through a turbine to 0.5 bar. It is then cooled to the same entropy as the inlet water before being compressed back to the inlet conditions. Calculate the following by using a steam table. (a) The steam state and properties after each process; (8 marks) (b) the heat transfer rates; (4 marks) (c) the network transferred; (4 marks) (d) the process thermal efficiency. (4 marks) (e) Calculate the possible thermodynamic efficiency of such a power generation cycle with the furnace operation condition fixed. Comment on the efficiency and practicality of the power generation cycle
