(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The water supply of a building is fed through a main pipe

6.00 cm in diameter. A 2.00-cm-diameter faucet tap, located

2.00 m above the main pipe, is observed to fill a 25.0-L

container in 30.0 s. (a) What is the speed at which the water

leaves the faucet? (b) What is the gauge pressure in the

6-cm main pipe? (Assume the faucet is the only “leak” in

the building.)

2. Relevant equations

3. The attempt at a solution

a)is easy.

Flux=Av

b)Apply Bernoulli's. I understand how to solve. But it rises a question: The energy associated with pressure is being converted in potential energy per volume when the water ascends to the faucet, so that the kinetic energy per volume is constant? Is this true?
