6.12 A horizontal water jet at 21°C impinges on a vertical- perpendicular plate. The discharge is 0.05 m³/s. If the external force required to hold the plate in place is 900 N, what is the velocity of the water? WILEY 6.13 PLUS A horizontal water jet at 21°C issues from a circular orifice in a large tank. The jet strikes a vertical plate that is normal to the axis of the jet. A force of 2.7 kN is needed to hold the plate in place against the action of the jet. If the pressure in the tank is 170 kPa gage at point A, what is the diameter of the jet just downstream of the orifice?
