 How is it calculated?
 At atmospheric pressure what is pressure
potential?
 How is Solute potential calculated?

2.  Determines movement of water, based on pressure
and solutes
 W = Wp + Ws
 Wp = 0
 Ws = -iCRT
 i = 1 for sucrose
 C = molar concentration
 R = 0.0831 Lbar/mol
 T = Temp in Kelvin
