Water towers store water above the level of consumers for times of heavy use, eliminating the need for high-speed pumps. How high above a user must the water level be to create a gauge pressure of 3.00 x 10^5 Pa?

Answer:


h=305.8103\ m

Step-by-step explanation:

Given:

  • gauge pressure desired,
    P_g=3* 10^5\ Pa

As we know that the layers of the liquid column exert pressure due to their weight which is given as:


P=\rho.g.h

where:


P= pressure due to liquid column


\rho= density of the liquid
=1000\ kg.m^(-3) for water


g= acceleration due to gravity


h= height of the liquid column

Similarly:


P_g=\rho.g.h


3* 10^(6)=1000* 9.81* h


h=305.8103\ m
