Given information
The diameter of the faucet is .
The pressure head is .
Step-by-step explanation
Step 1.
Bernoulli's equation is related to the law of conservation of energy and it indicates the relation between pressure, speed and the height of a fluid.
The pressure head is considered as the initial height of water and at this height the speed of water is .
The formula for the speed of water from Bernoulli's equation is
Here, is the final pressure, is the final speed, is the density, is the acceleration due to gravity, is the initial pressure, is the final height, is the initial speed and is the initial height.
