Question

A submersible pump is put under the water at the bottom of a well and is used to push water up through a pipe. What minimum output gauge pressure must the pump generate to make the water reach the nozzle at ground level, 75 m above the pump?

    Answer:

    The Required pressure for this situation is P= 735000Pa

    Explanation:

    In Determining the required pressure in this situation we use two equations

    First one is

    F = mg = (ρhA)g

    And Second one is

    P = F/A = (ρhAg)/A Where P is pressure

    We get

    P = ρhg  

    since g = 9.8 m/s and h is given that is 75m and ρ = 1000 kg/m^3

    so

    P = (9.8 m/s)(1000 kg/m^3)(75) we get

    P = 735000 Pa
