Water Pressure Calculator
If you want to determine the flow or pressure of the water from pipes or taps, you can use our water pressure calculator.
Before explaining the water pressure, let us elaborate the term pressure first. In physics, pressure is an external force applied upright to the object's surface per area, where the force is drawn. Now, the water pressure can be defined as the flow of water from the pipe or tap.
At the same time, pressure is applied to drive the water into the pipe. The SI unit used to symbolize pressure is Pascal (Pa). In other words, the water pressure is determined as a force that causes and controls the water flow. The pressure applied by the liquid is also known as hydrostatic pressure.

Formula of Water Pressure Calculator
To instantly determine the water pressure, you can jump to our calculator, or you can use the formula listed below:
P = ρ x g x h
Where,
P = Pressure of water
ρ = Density of water = 997 kg/m³
g = Gravitational constant = 9.81 ms-2
h = height (from the surface to the endpoint where the water has to be delivered)
Example
For a more transparent and precise understanding of a concept, let us have an example below;
Suppose a tank having a height of 5m is to be filled with water. Then calculate the required amount of pressure used to flow the water to the tank.
Given data
h = 5m
ρ = 997 kg/m³
g = 9.81 ms
To Find
Water pressure = ?
Solution
To find out the acceleration due to gravity on the moon, we will use the formula listed below:
P = ρ x g x h
Putting values in the formula:
P = 997 x 9.81 x 5 = 48,902 Pa
48,902 Pa is the required amount of pressure used to flow the water to the tank.
Note:
If you want to calculate absolute pressure, you can use our Absolute Pressure Calculator.
