- Q1. What would be the effect on the calculated force on the flat plate if the jet were to leave the plate not horizontal but inclined upwards at an angle of 1 °? If the experiment were to be repeated with the vane in the form of a cone with an included angle of 60° (half angle 30°), how would you expect the results to appear?arrow_forwardA 3-in-diameter horizontal jet of water, with velocity 140 ft/s, strikes a bent plate, which deflects the water by 135° from its original direction. How much force is required to hold the plate against the water stream and what is its direction?
