Determine the minimum gauge pressure needed in the water pipe leading into a building if water is to come out of a faucet on the fourteenth floor, 43

The  gauge pressure is  

Explanation:

From the question we are told that

     The height of the 14th floor from the point where the water entered the building  is  h = 43 m

The  gauge pressure is  mathematically represented as

Where  the m is the mass of the water which is  mathematically represented as  

Where   is the density of the water which has a constant value of   and this standard value of density the volume is   so

Thus
