A real turbine with a mass flow rate of 5.0 kg/s of steam has inlet conditions of 6.0 MPa and 700 oC, and exit conditions of saturated vapor at 50 kPa. If the power output of the turbine is 5.0 MW, determine the rate of heat loss from the turbine to 3 significant figures in kW. Assume the inlet/outlet kinetic and potential energy changes are negligible.

Determine the increase in specific entropy of the steam as it flows through the turbine (units of kJ/kg K).

A small-scale pumped storage system pumps water from a lake to a higher elevation reservoir at times for use in a small hydroelectric turbine at times of high demand. The high-elevation reservoir is 45 meters above the height of the lake. For an energy storage capacity of 850 kWh what is the amount of water that needs to be stored at the high elevation reservoir in units of Mg (millions of grams)? Provide answer to 4 significant figures.
