The presssure of water at the basement of a building is 196000 pascals and at the third floor it is 98,000pascals. Find the height of the third floor from the basement .

Explanation

Let x meter be the height of the third floor from the basement
So, Here we have x`rho`g=`delta`P
i.e. `x*10^3`*9.8=(196000-98000) pascal
=98,000`N/m^2`
x=98000/`10^3*9.8=10m
