The water supply of a building is fed by a main pipe 6.00cm in diameter. A 2.00cm diameter tap is located 2.00m above the main pipe. When the tap is turned on it fills a 25.0L container in 30.0s if no other taps are turned on at the similar time.
a) What is the speed at which the water leaves the tap?
b) What is the gauge pressure in the 6cm main pipe?
