## Homework Statement

The water supply of a building is fed through 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 same time.

a) What is the speed at which the water leaves the tap?

b) What is the gauge pressure in the 6cm main pipe?

## Homework Equations

P1+0.5pv1^2 + pgy1 = P2 +0.5pv2^2 + pgy2

Pg = Ps - Pa

## The Attempt at a Solution

I solved part (a) easily enough by dividing 25 by 30 to get 0.833 L/s

and I'm sure i have to use Bernoulli's equation to solve this but have been having problems understanding the equation and the concept behind it and how i would use this in the particular problem I'm faced with.

Thanks for helping
