When the hydraulic conductivity ks = 10 mm/hr; effective matrix potential ns = 20 mm, and rainfall intensity i = 30 mm/hr , determine the amount of runoff generated when the runoff rate reaches 15 mm/hr? ( 2.7 mm or 0.21 mm or 18 mm or 0.67 mm)

The amount of potential energy possessed by an elevated object is equal to
