Question

A horizontal jet of oil (SG = 0.6) strikes a curved blade that turns the flow through an angle of 180⁰. The jet area is 1000 mm² and its speed from a stationary nozzle is 35 m/s. The blade is moving toward the nozzle at 15 m/s. Determine the force on the blade from the jet (a) in horizontal direction, Rx in kN and (b) in vertical direction, Ry in kN. [Consider the relative jet velocity in calculations]
