Question

2) 25 points. Dominion Power has ~18 plants in Virginia that produce power driven by steam produced by burning natural gas. Consider one plant where the flow rate of steam

is 10 kg/s.The linear velocity of the steam is 50 m/s. The steam leaves the turbine at a point 10 m below the inlet and a linear velocity of 300 m/s. The work output of the turbine is 0.5 MW and there is some heat loss from the system of 100 kW. Write out the energy balance for this system and use it to estimate the change in enthalpy of the power generator.
