Air, with a mass flow rate of 8.0 kg/s, enters a gas turbine. The enthalpy of the air entering the turbine is 825 kJ/kg, the velocity of the air is 325 m/s, and the height of the air above the ground is 2.5 m. The acceleration due to gravity is 9.81 m/s2. Determine the rate at which energy is being transferred into the gas turbine via mass flow by this air.

Given: m? = 8.0 kg/s; h = 825 kJ/kg; V = 325 m/s; z = 2.5 m; g = 9.81 m/s2 What will be an ideal response?
