7.) A stream of water traveling at 20 m/s at the rate of 600 liters per min. is directed horizontally against a vertical wall. The water spreads out along the wall without splashing back. What force does this stream exert on the wall? Note that the density of water is 1000 kg/cubic meter, and 1 liter = 10(negative 3 power) (cubic meter. (200 N)

Consider a mountain stream with an effective head of 20 meters (m) and a flow rate of 800 liters per seconds. 3 How much power could Assume plant efficiency of 75% and the density of water is 1000 kg/m the hydro power plant generate?
Water is accelerated by a nozzle to an average speed of 20 m/s, and strikes a stationary vertical plate at a rate of 10 kg/s with a normal velocity of 20 m/s. After the strike, the water stream splatters off in all directions in the plan of the plate. Determine the force needed to prevent the plate from moving horizontally due to the water stream. Assume that the density of water is =1000 kg/m3
V cart Nozzle V. jet- 4. (20 pts) A 3-cm-diameter water jet moving at 40 m/s velocity in x-direction strikes the vertical back surface of a cart moving horizontally at a constant speed of 10 m/s in the flow direction. After the strike, the water stream splatters off in all directions in the plane of the back surface. Using the moving control volume indicated with dashed lines in the figure, determine: Waterjeti F. Rx X a) The relative velocity and...
8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...
