Question

what is gauge pressure.How it can be calculated?​

Answer 1

Answer:

the amount by which the pressure measured in a fluid exceeds that of the atmosphere.

Hydrostatic pressure at any height below the water surface is calculated by P=hdg where h is the height below the open water surface, d is the density of water and g is the acceleration due to gravity. So if you want to calculate gauge pressure at height h then use formula P=hdg+P∘ where P∘ is atmospheric pressure.

Answer 2

_______________________________________

Gauge Pressure

It is the pressure measured related to atmospheric pressure

Formula

Gauge Pressure = Absolute Pressure - Atmospheric Pressure
