    Answer:

    The gauge pressure is 147000 Pa.

    Explanation:

    Height, h = 15 m

    density of water, d= 1000 kg/m^3

    gravity, g = 9.8 m/s^2

    The gauge pressure is the pressure exerted by the fluid.

    The pressure exerted by the fluid is given by

    P  = h d g

    P = 15 x 1000 x 9.8 =  147000 Pa

    Answer:

    The gauge pressure is equal to 147 kPa.

    Explanation:

    The pressure exerted by fluid is given by :

    P=\rho gh

    Where

    \rho is density of water

    h is height

    So, put all the values,

    P=1000\times 9.8\times 15\\\\P=147000\ Pa

    or

    P = 147 kPa

    So, the gauge pressure is equal to 147 kPa.
