A steam engine consists of a boiler connected to a turbine. The boiler tank has a volume of 100 L and initially contains saturated liquid with a very small amount of vapor at 100 kPa. Heat is now added by the burner, and the pressure regulator does not open before the boiler pressure reaches 700 kPa, which keeps it constant. The vapor leaving the boiler tank passes through a turbine and is discharged to the atmosphere as a saturated vapor at 100 kPa. The burner is turned off when no more liquid is present in the boiler. Find the total turbine work and the total heat transfer to the boiler for this process. Assume the turbine is adiabatic and the change in kinetic and potential energy across the turbine is negligible.
