Answer:
The average force exerted on a person assuming that the water splashes sideways in all directions is 150 newtons.
Step-by-step explanation:
From Fluid Mechanics and Newton's Laws we know that water stream is an example of a variable mass system at constant speed and the magnitude of the net force done by the water splash (
), measured in newtons, is given by the following expression:
(Eq. 1)
Where:
- Density of water, measured in kilograms per cubic meter.
- Volume flow rate, measured in cubic meters per second.
- Flow velocity, measured in meters per second.
If we know that
,
and
, the average force exerted on a person is:


The average force exerted on a person assuming that the water splashes sideways in all directions is 150 newtons.
