A 3-in-diameter horizontal jet of water, with velocity V = 45 fl/s, strikes a bent plate, which deflects the water by 150° from its original direction. What magnitude force Fg is required to hold the plate against the water stream and what is the direction of the force? Disregard frictional losses and gravitational effects. (Jet generally means an extemal stream which is "open to atmosphere".)

Diagram should be added (to show the force). To solve the problem ,use the momentum concept.

A jet of air having velocity V₁ and cross-sectional area A₁ strikes an inclined plate as shown in the figure. Neglect any effects of viscosity. V₁ (a) Find V₂ and V3 in terms of V₁. Note that the pressure is patm everywhere. (b) Because viscous effects are negligible, there is no way for the air to exert a force on the plate in the tangential (z) direction. Using the coordinate system in the figure, find A₂ and A3 in terms of A₁ and 0. (c) For V₁ = 50 m/s, A₁ = 5 x 10-4 m², and 0 = 60°, find the force required to hold the plate in place. Neglect the weight of the plate. Recall that pair = 1.225 kg/m³.

A horizontal water jet impinges on a vertical-perpendicular plate. The discharge is 0.2 m/s. If the horizontal external force required to hold the plate in place is 9.7 kN, what is the velocity of the water (m/s)? water density = 1000 kg/m3. Jet area = 0.1 m2. 48.5 %3D

Question 5 A 3 in diameter horizontal water jet having a velocity of 140 ft/s strikes a curved plate, which deflects the water 180° at the same speed. Ignoring the frictional effects, determine the force required to hold the plate against the water stream. (Ans: 3729 Ib) Water jet 140 fvs 13.in 140 fvs
