The water supply of a building is fed through a main pipe 6.00 cm in diameter. A 3.00 cm diameter faucet tap, located 1.00 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 6.00 cm main pipe? (Assume the faucet is the only "leak" in the building.)
