Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_39

4/39 A jet of fluid with cross-sectional area \(A\) and mass density \(\rho\) issues from the nozzle with a velocity \(v\) and impinges on the inclined trough shown in section. Some of the fluid is diverted in each of the two directions. If the trough is smooth, the velocity of both diverted streams remains \(v\), and the only force which can be exerted on the trough is normal to the bottom surface. Hence, the trough will be held in position by forces whose resultant is \(F\) normal to the trough. By writing impulse-momentum equations for the directions along and normal to the trough, determine the force \(F\) required to support the trough. Also find the volume rates of flow \(Q_1\) and \(Q_2\) for the two streams.
