A holding tank initially contains 2 kg of steam at 5 bar and 300C. Over the course of the day, 1000 kJ of heat is lost to the surroundings and the pressure drops to 4 bar. Determine the temperature and quality of the steam at the end of the day.

After some time, the insulation breaks down resulting in a heat loss of 80 kJ for each kg of steam passing through the turbine. (It may be assumed that the heat is transferred out at 600C.) b) Find the work generated (per kg) by the turbine. (10 pts) c) Determine the efficiency of the turbine
