A wind turbine with a diameter of 100 ft operates during a 24-h period in which the wind velocity may be approximated by half a sine wave as V(theta)=V(m)sin(pi*theta/24), where theta is time in hours and V(m)= 10^5 ft/h. The wind density is 0.076 lbm/ft^3. Calculate (a) the theoretical maximum turbine energy during that 24-h period, in foot-pound force and kilowatt hour, and (b) the wind mean energy velocity, in feet per hour.
