A jet airplane is travelling at `200 ms^(-1)` . The engine of the plane takes in 250 `m^(3)` of air of mass 32 kg each second . The air is used to burn 3 kg of fuel each second . The energy is used to compress the products of combustion to eject them at the rear of the plane at `500 ms^(-1)` relative to the plane . Find the power of the jet plane in H.P.(1 H.P = 746 W). [Hint : Resultant thrust = forward thrust - backward thrust and power = force `xx` velocity ] |
