Question

The tank of water supply is at height of 50m .Find the pressure in a pipe at the top of house 10m high.

Answer 1

pressure difference between the surface of water and pipe = ρ g h

pressure = Atm + ρ g h = density * acceleration due to gravity * height
       = 1.013 * 10⁵ Pa + 1000 kg/m³ * 9.81 m/sec² * (50 - 10) m
       = 4, 93, 700 Pa or N/m²
       = 4.873  atmospheres
