Question

Numerical Problem
The pressure in water pipe at the ground floor of a building is 120000 Pa, whereas the pressure on the thurd floor is 30000 Pa. Calculate the height of third floor.

Answer 1

Difference in pressure of water at ground floor and third floor = (120000-30000)=90000 Pa.
Let 'h' be the height of third floor.
Therefore, Pressure of water due to height h = hqg = h x 1000 x 10 = 10000 h
10000 h = 90000
h = 9m.
