III. Steam enters a turbine operating at steady state with a mass flow rate of 10 kg/min, a specific

enthalpy of 3100 kJ/kg, and a velocity of 30 m/s. At the exit, the specific enthalpy is 2300 kJ/kg

and the velocity is 45 m/s. The elevation of the inlet is 3 m higher than at the exit. Heat transfer

from the turbine to the 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. (Please, use problem-solving

techniques for this problem, KNOWN, FIND,...)
