Two kilograms of water execute a carnot power cycle. during
the isothermal expansion, the water is heated until it is
asaturated vapor from an initial state where the pressure is 40
barand the quality is 15 %. the vapor then expands adiabaticallyto
a pressure of 1.5 bar while doing 491.5 kj/kg of work.
(a.) sketch the cycle on p-v coordinates
(b.) evaluate the heat and work for each process, in kj.
(c.) evaluate the thermal efficiency.
