Steam enters a turbine operating at steady state with a mass flow rate of 8.7 kg min1, a specific enthalpy of 3470 kJ kg and a velocity of 26 m s. At the exit the specific enthalpy is 2310 kJ kg' and the velocity is 46 m s1. The elevation of the inlet is 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

Question
Transcribed Image Text:Steam enters a turbine operating at steady state with a mass flow rate of 8.7 kg min1, a specific enthalpy of 3470 kJ kg' and a velocity of 26 m s1.
At the exit the specific enthalpy is 2310 kJ kg' and the velocity is 46 ms.
The elevation of the inlet is 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
