A 3-blade wind turbine with a diameter of 16 m spins at 35 rpm at a 5000 m elevation where the average wind speed is 30 km/hr. The atmospheric pressure and temperature at that location are 98 kPa and -10 oC, respectively. There is a rotating wake behind the turbine. Neglecting the frictional drag, calculate the maximum power coefficient and maximum power.

A wheels starts from rest and speeds up to 1500 rpm in 120 s. a) Find the angular acceleration of the wheel assumed constant. b) Find the number revolutions it makes during this time. c) Find the time it takes for the wheel to complete its 10th complete revolution. ( hint: Find angular velocity at the end 9 revolution, which becomes W1 for the 10th revolution) Remember there are 2 radius radians in a revolution.
