Assuming that interconnected pores in a soil can be represented as a continuous
capillary tubes (Fig. 1), derive h as a function of dand then estimate how high the water
rise in the soil consisting of silt(with pore diameter (d) of 10 µm.)The surface tension of
water = 72 mN/m. Explain whether this estimation is still valid for tortuous layer structures.
