a horizontal water jet impinges against a vertical flat plate at 27 ft/s and splashes off the sides in the vertical plane. if a horizontal force of 500 lbf is required to hold the plate against the water stream, determine the volume flow rate of the water. take the density of water to be 62.4 lbm/ft3. the volume flow rate of the water is 1 numeric responseedit unavailable. 1 incorrect.ft3/s.

Respuesta :

The water moves at a rate of 9.548 cubic feet per second. In order to answer this question, we must apply the conservation of linear momentum to a system of water jets and walls.

How to use a water jet-wall system to apply the laws of linear momentum conservation

In order to answer this question, we must apply the conservation of linear momentum to a system of water jets and walls.

Since the system is in equilibrium, the horizontal force (), measured in pounds-force, applied to the wall must be equal to the force generated by the water jet:

F= p.V.u/ gc

Where:

p is the weight of water in pounds per cubic foot.

In cubic feet per second, V stands for volume flow rate.

u is the water jet's velocity in feet per second.

gc stands for the conversion factor and measures the force in pounds per square second.

V= 9.548 ft³ / s

The water moves at a rate of 9.548 cubic feet per second.
