A 7-cm diameter vertical water jet is injected upwards by a nozzle at a speed of 15 m/s. Determine the maximum weight of a flat plate that can be supported by this water jet at a height of 2 m from the nozzle.

Q:A 7-cm diameter vertical water jet is injected upwards by a nozzle at a speed of 15 m/s.Determine the maximum weight of a flat plate that can be supported by this water jet at aheight of 2 m from the nozzle.Answer:771N SolutionStep 1 of 4We need to find the weight of the flat plate which is supported by the stream of water comingvertically out of a nozzle of diameter 7cm.The plate is held at 2m from the nozzle. The water as it hits the plate, it splatters and covers theentire area of the plate. The thrust given by the water balances the weight of the plate, thusholding the plate at 2m from nozzle.Assumptions: 1. The water is incompressible 2. Friction between the water and air is negligible 3. Momentum-flux correction is negligible 4. Thin region below the flat plate is taken as the control volume.Data given:1.Density of water=2.3.Height,4.Velocity of water at the nozzle,
