Enter the pressure potential and the solute potential into the calculator to determine the water potential.
Water Potential Formula
The following equation is used to calculate a water potential.
Ψ = Ψp + Ψs
- Where Ψ is the water potential
- Ψp is the pressure potential
- Ψs is the solute potential
Water Potential Definition
A water potential is a measure of the waters potential to perform work.
Water Potential Example
How to calculate water potential?
- First, determine the pressure potential.
Calculate the pressure potential.
- Next, determine the solute potential.
Calculate the solute potential.
- Finally, calculate the water potential.
Calculate the water potential using the formula above.
Water potential is a measure of water’s ability or potential to do work. Doing work involves applying a force strong enough to cause another object, or solution, to be displaced. Water potential at atmospheric pressure is 0. Often times water potential is analyzed as it relates to movement through cell membranes.
A pressure potential is the amount of work a solution can produce due to an outward pressure acting on it.
Like a water potential, the solute potential is the ability of the solute to do work through movement.
