A piston driven steam engine and boiler runs according to a modified Rankine cycle. If the steam leaves the boiler at 150 degrees Celsius, and 100 kPa, determine the engine's efficiency. Note that the specific volume at this pressure is 0.001043 m3/kg, and the enthalpy is 417.51 kj/kg. also, note that there is no condenser or pump. The boiler is sealed, and not replenished while the exhaust steam exits to open atmosphere.
