dt A jet of water from a tube of area of cross section A strikes a wall normally with a velocity Vand then flows down along the wall The force exerted on the wall is F AV d If water bounces back with velocity u then F Adv v u If water bounces back with same velocity V then F 2A dv If water strikes at an angle 0 to the surface of wall and reflects then F 2A dv sin 0
