Force from a Jet of Water A jet of fluid striking a vane exerts a force on the vane it is equal and opposite to the vane. It is the equal and opposite force of the fluid momentum change that accompanies such a flow. For different weights, the water flow rate is adjusted so the platform stays at the zero reading. These values are given below Q, ftA3/s 0045 0069 0011 0107 0116 0041 0076 0113 0146 Weight Angle, deg...

13. A centrifugal pump whose outer diameter is twice the inner diameter, runs at 600 rpm. The radial gh the pump is constant at 2.5 m/s and the flow is radial at the pump inlet. The rotor vanes are curved back at exit at an angle of 40° to the tangent. If the outer diameter of the rotor is 500 mm and the blade width is 50 mm at exit, the tangential component of absolute velocity at rotor exit (in...
