Students have asked these similar questions
An elbow deflects water upward and discharges it to the atmosphere at a specific rate. Determine the gage pressure at the inlet of the elbow and the anchoring force needed to hold the elbow in place. (gage pressure at the outlet is zero)
I can't figure out what I am missing here can you help me figure this out please?
A jet of 50mm diameter impinges on a curved vane and is deflected through an angle of 175 degree. The vane moves in the same direction as that of jet with a velocity of 35m/s. if the rate of flow is 170 L/s, determine the component of force on the vane in the direction of motion. How much would be the power developed by the vane and what would be the water efficiency? Neglect friction.
