1. Fluid with 1040 Kg/m3 density is flowing steadily through the rectangular box shown. Given 󰇍󰇍󰇍1 = 3𝑖 m/s, 𝑉󰇍󰇍󰇍2 = 6j m/s, determine velocity 𝑉 󰇍 󰇍3 A1= 0.046 m2, A2= 0.009 m2, A3= 0.056 m2, 𝑉 component.

2. Water flows steadily past a porous flat plate. Constant suction is applied along the porous section. The velocity profile at section cd is

Evaluate the mass flow rate across section bc.

3. A 30° reducing elbow is shown. The fluid is water. Evaluate the components of force that must be provided by the adjacent pipes to keep the elbow from moving.

4. A jet of water is directed against a vane, which could be a blade in a turbine or in any other piece of hydraulic machinery. The water leaves the stationary 40-mm-diameter nozzle with a speed of 25 m/s and enters the vane tangent to the surface at A. The inside surface of the vane at B makes angle θ = 150° with the x direction. Compute the force that must be applied to maintain the vane speed constant at U = 5 m/s....
