A steam power plant for an automotive vehicle is proposed as shown. The boiler has a volume of 50 litres and initially contains 90% liquid and 10% vapor by volume at 100kPa. The burner is now turned on and when the pressure in the boiler reaches 700kPa the pressure regulating valve holds the boiler pressure constant at 700kPa and saturated vapor at this pressure is passed to the turbine. Saturated vapor steam at 100 kPa exits the turbine and is discharged to the atmosphere. When the liquid in the boiler is depleted the burner shuts off automatically. Calculate the total work output of the turbine and total heat transfer for one charge of the boiler
