Enter the height of the fluid column, the density of the fluid, and the acceleration due to gravity into the calculator to determine the pressure potential.
Pressure Potential Formula
The following formula is used to calculate the pressure potential:
PP = ρ * g * h
Variables:
- PP is the pressure potential (Pascals)
- ρ is the density of the fluid (kg/m³)
- g is the acceleration due to gravity (m/s²)
- h is the height of the fluid column (meters)
To calculate the pressure potential, multiply the density of the fluid by the acceleration due to gravity and the height of the fluid column.
What is Pressure Potential?
Pressure potential is the potential energy per unit volume that a fluid possesses due to its position in a gravitational field. It is a measure of the energy that is available to do work due to the elevation of the fluid. This concept is important in fields such as hydrology, civil engineering, and fluid mechanics.
How to Calculate Pressure Potential?
The following steps outline how to calculate the Pressure Potential.
- First, determine the density of the fluid (ρ) in kilograms per cubic meter.
- Next, determine the acceleration due to gravity (g) in meters per second squared, typically 9.81 m/s² on Earth.
- Next, determine the height of the fluid column (h) in meters.
- Next, gather the formula from above = PP = ρ * g * h.
- Finally, calculate the Pressure Potential (PP) in Pascals.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Density of the fluid (ρ) = 1000 kg/m³
Acceleration due to gravity (g) = 9.81 m/s²
Height of the fluid column (h) = 10 meters
