Ideal osmotic term = −iCRT, R = 0.008314462618 L·MPa/(mol·K). Gravity ≈ 0.00980665 MPa per meter; sum with entered pressure and matric components.
How to use Water Potential Calculator
- Enter quantities in the units shown and identify the observation period, product basis or geometric model.
- Supply targets, prices and management assumptions from an appropriate external plan; the calculator does not choose them.
- Select Calculate and read the result with its limitations. Reset restores the starting form.
