I need help with flow rate please!!!!!!!

1. The problem statement, all variables and given/known data

A pump at ground level creates a gauge pressure of 102 kPa in the water line supplying an apartment building. The water leaves the tank into a pipe at a negligible speed. It travels 10m up through the building and exits through a faucet. The cross sectional area of the faucet is 2.0cm2. (use for water density ρ=1000kg/m3 and acceleration of g=10m/s2). What is the volume flow rate of water leaving the faucet in cm3/s ?

2. Relevant equations

3. The attempt at a solution
Q=A+((2)[(Pa-Pb)-(pgh)]/p)^1/2

Hi alexito01!

Can you put the figures in, please?

It's difficult for us to work out what the letters refer to.

Re: I need help with flow rate please!!!!!!!

I have a question: is this a volumetric pump?

Why is there a plus sign after A?
Where has the 102 kPa gone to?
What's Pa and Pb? They aren't mentioned in the statement.
