A jet pump is created by bringing a faster flow concentrical

A jet pump is created by bringing a faster flow concentrically in the center of a slower flow. Both streams are water. The faster jet area is 0.01 m^2 and jet velocity is 32 m/s. The secondary flow through the outer duct is at 3 m/s. The exit area and the total inlet area, which includes the jet area and the surrounding duct area through which the slower flow enters, is 0.07 m^2. The water is thoroughly mixed and leaves the jet pump at a uniform velocity as determined from HW#5. Assume the pressure at location 1 is uniform, the distance from inlet to exit is 0.5 m and the shear stress is 300 Pa. Determine P_2-P_1.

Solution

The answer of the following question is as follows

P2-P1=378 N/m2

When the pressure is uniform,the distance from inlet to exit is .5 m and the shear stress is 300 Pa
