4.75 A shallow circular dish has a sharp-edged orifice at its center. A water jet, of speed V, strikes the dish con- centrically. Obtain an expression for the external force needed to hold the dish in place if the jet issuing from the orifice also has speed V. Evaluate the force for V-5 m/s D-100 mm, and d-25 mm. Plot the required force as a function of the angle θ (0 θ 90°) with diameter ratio as a parameter for a suitable range of diameter d
θ = 45° P4.75
