Document Summary
Data and equations are provided at the end of this paper: (5 marks) (a) write down the expression for the inequality of clausius. Explain briefly. (b) the schematic shows a power plant operating with water. The pressure in the boiler is constant and equals to 0. 15 mpa with qualities x1 = 0 % and x2 =100 %. The pressure in the condenser is constant and equals to 20 kpa with qualities x3 = The processes in the turbine and in the pump are adiabatic. Determine whether the cycle is possible or reversible or impossible. Explain briefly: (5 marks) water is compressed in an isothermal and reversible steady state process. Initially the pressure is p1 = 0. 6 mpa and the temperature is t1 = 180 c; the final state is saturated vapor with quality xl = 1. 0. The mass flow rate is m = 0. 5 kg/s.
