Question Solved1 Answer A 10 cm diameter free jet of water having a velocity of 30 m/s impinges on a plane, smooth plate at angle of 45° to the normal to the plate. (a) What will be the force due to jet impingement on the plate and work done per second when (i) the plate is stationary, and (ii) when moving in the direction of the jet at 6.0 m/s velocity. (b) What will be the force due to jet on the plate when the plate is moving against the jet direction at 6.0 m/s velocity?
