A person is filling a knee-high bucket with water using a garden hose and holding it such that water discharges from the hose at the level of his waist. Someone suggests that the bucket will fill faster if the hose is lowered such that water discharges from the hose at the knee level. Do you agree with this suggestion? Explain. Disregard any frictional effects.
In this question, we need to check if there is increase in velocity of water flow if the height is reduced
Step 2 :
We can explain this using Bernoulli’s equation
Assume it is at the ground
We shall assume this to same as atmospheric pressure
With the assumptions considered we have
Thus we have obtained velocity at height above the knee level
