I need help with flow rate please

    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

    Hi alexito01! :smile:

    Can you put the figures in, please?

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

    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.
