Question

Consult Interactive Solution 7.10 for a review of problem-solving skills that are involved in this problem. A stream of water strikes a stationary turbine blade horizontally, as the drawing illustrates. The incident water stream has a velocity of 16.0 m/s, while the exiting water stream has a velocity of -16.0 m/s. The mass of water per second that strikes the blade is 36.0 kg/s. Find the magnitude of the average force exerted on the water by the blade.

Answer 1

`F=1152N`

Step-by-step explanation:

From the question we are told that:

Mass/one sec
`m=36.0kg/s`

Incident water stream
`v=16.0m/s`

Exiting water stream
`v'=-16.0m/s`

Generally the equation for Force is mathematically given by

`F=(mv-mu)/(t)`

`F=(36(-16-16))/(1)`

`F=1152N`
