An airplane flies at 300 km/h at sea level at 20°C. The propeller diameter is 1.8 m, and the velocity of the air through the propeller is 360 km/hr. Find:
(a) The slipstream velocity relative to the airplane.
(b) The thrust.
(c) The power input.
(d) The power output.
(e) The efficiency.
(f) The pressure difference across the propeller disk.
