A pipe 10 cm in diameter and 400 m long has a nozzle fixed at the discharge end. The nozzle discharges at atmospheric pressure. If the pipe is horizontal and the head at the pipe inlet is 45 m, determine the maximum power that could be transmitted. What would be the corresponding size of the nozzle? (Assume f = 0.02).
