solve part E with clear steps

A wind turbine with a rotor diameter of 50m operates on an average wind speed of 10m/s. The wind turbine converts 25% of the wind energy into electrical power. a) Assuming air as an ideal gas at 25C,1 bar, and a molar mass of 29g/mol, show that the air density is 1.17kg/m3 (ideal gas: PV=RT ) b) Determine the mass flow rate of air passing through the turbine in kg/s c) Find the total rate of kinetic energy in MW available in the air passing through the turbine d) Determine the produced electrical power in MW e) If the produced electrical power is used for street electrical bulbs of 0.25kW each, how many electrical bulbs can be lighted by the produced power
