Add pressure potential (Ψ_p) and solute potential (Ψ_s) to determine the total water potential (Ψv). The Water Potential Calculator is a handy tool to compute the movement of water in biological systems. Water potential (Ψ) indicates the potential energy of water and predicts its direction of movement.
It is crucial for understanding processes like osmosis, nutrient uptake in plants, and water transport. This measure combines pressure potential and solute potential, providing insights into the behavior of water in both open and closed systems.
Formula:
Ψ = Ψp + Ψs
| Variable | Definition | Units |
