Figure P6.8 shows a tube with two sections, each with a different diameter, d1 and d2. The tube is placed in the water bath as shown.

(a) How high above the phreatic surface will the water rise in the tube due to capillarity? What is the pore pressure at the surface of the capillary rise?

(b) If the capillary rise you found in part (a) occurred in a soil, what would you estimate as the soil's D10?

d2 = 0.4 mm d = 0.6 mm 5 cm Different horizontal and vertical scales
