Water Pressure Calculator

Formula

The formula to calculate the water pressure (P) is:

\[ P = p \cdot g \cdot h \]

Where:

\(P\) is the water pressure (Pascals)
\(p\) is the density of the fluid (kg/m³)
\(g\) is the acceleration due to gravity (m/s²)
\(h\) is the depth of the object in the water (meters)

What is Water Pressure?

Water pressure is the total pressure acting on an object in submerged water that arises from the water density and force of gravity. It is calculated by multiplying the density of the fluid by the acceleration due to gravity and then by the depth of the object in the water. Water pressure increases with depth due to the weight of the water above.

Example Calculation

Let's assume the following values for fresh water:

Density of the Fluid (p) = 997.0474 kg/m³
Acceleration due to Gravity (g) = 9.81 m/s²
Depth (h) = 10 meters

Using the formula to calculate the water pressure (P):

\[ P = p \cdot g \cdot h = 997.0474 \cdot 9.81 \cdot 10 = 97810.36 \text{ Pascals (Pa)} \]

The Water Pressure (P) is 97,810.36 Pascals (Pa).
