Steam enters a turbine with a velocity 120 m/s at 600°C and 6000 kPa. The steam leaves the turbine as saturated vapor at 200 kPa with a velocity of 180 m/s. Heat is transferred from the turbine to the surroundings in the amount of 30 kJ for every kilogram of steam flowing through the turbine. The mass flow rate of steam through the turbine is 20 kg/s (1 kJ/kg = 1000 m2/s2)
A) Find the work done by the steam in the turbine in kW
B) Determine the flow area at the entrance to the turbine in m^2
