the speed of water at the tap of lower storey is more tjan that in the upper storey
Answers
Answer:
Simply stated, the weight of water above the first floor.
For every 2.31 feet (27.72 inches) of water above the elevation of a given point, the pressure will increase by 1.0 pounds per square inch (psi).
Thus the first floor may have 45 psi at the kitchen sink and the bathroom upstairs, nine feet above, will have 49.9 psi when nothing is flowing.
Once any faucet is opened, the water pressure will drop all across the system, but the elevational pressure differences remain constant, except for friction losses of pipe and fittings along the way.
To illustrate a more extreme example, a 1,000 foot tall skyscraper will routinely see water pressures 433 psi higher than at the bottom. Of course with street water pressures in the range of 100 psi, water pressure booster pumps are used to lift the water and maintain the pressure.
hope this will help you.
Answer:
It's due to the speed of water as length of the pipe increases the speed of the water increases
