The value of water potential is calculated as :
Water potential = Solute potential + Pressure Potential
where, solute potential is determined by the concentration of salt in water and pressure potential value is equivalent to Hydrostatic pressure determined relative to atmospheric pressure.
When a solution is maintained at atmospheric pressure the pressure potential is nullified due to no hydrostatic pressure at atmospheric pressure.
Hence, the equation now would read as
Water potential = Solute potential + 0
Resulting in,
Water potential = Solute potential
