A jet of water issues from a nozzle at a speed of 6 m/s and strikes a stationary flat plate oriented normal to the jet, as shown in Figure 1. The exit area of the nozzle is 645 mm2. Ignore friction losses and assume all pressures are atmospheric (zero gauge pressure). (a, 15%) What is the total horizontal force (-Rx) on the plate from the fluid? (b, 20%) Suppose the nozzle is moving at a speed of 1.5 m/s to the left relative to the ground. If the water issues out at 6 m/s relative to the nozzle, what is the horizontal force on the plate (-Rx)? (c, 20%) What is the horizontal force on the plate (-Rx) if in addition to conditions from Part b, the plate is moving at a uniform speed of 3 m/s to the right relative to the ground?
