Steam enters a turbine operating at steady state with a mass flow rate of 10.1 kg min1, a specific enthalpy of 3130 kJ kg and a velocity of 22 m s!. At the exit the specific enthalpy is 2190 kJ kg' and the velocity is 40 ms1. The elevation of the inlet is 3.2 m higher than at the exit. Heat transfer from the turbine to its surroundings occurs at a rate of 1.1 kJ per kg of steam flowing. Let g = 9.81 m s2. Determine the power developed by the turbine in kW.

Sem2 Wks6-8 Part2: Turbine
Steam enters a turbine operating at steady state with a mass flow rate of 10.1 kg min-1, a specific enthalpy of 3130 kJ kgl and a
velocity of 22 ms.
At the exit the specific enthalpy is 2190 kJ kg and the velocity is 40 m s1.
The elevation of the inlet is 3.2 m higher than at the exit.
Heat transfer from the turbine to its surroundings occurs at a rate of 1.1 kJ per kg of steam flowing.
Let g = 9.81 m s2.
Determine the power developed by the turbine in kW.
Power =
kW
