Use Burdine's (1953) equation from the handout (the statistical capillary tube model equation with the values of b, r, and m assumed by Burdine) to mathematically derive a relationship for the hydraulic conductivity function that is based on the SWRC model of Brooks and Corey (1964).
Question 2
A sluice gate controls flow in open channels. At
sections 1 and 2, the flow is uniform and the
pressure is hydrostatic. Neglecting bottom
friction and atmospheric pressure, calculate the
velocities V1 and V2, and the horizontal force, F,
required to hold the gate if h1 = 6m, h2 = 1m, and
b = 5m.

Question 1
A pipeline 30 m long connects two tanks which
have a difference of water level of 12 m. The first
10 m of pipeline from the upper tank is of 40 mm
diameter and the next 20 m is of 60 mm diameter.
At the change of section, a valve is fitted.
Calculate the rate of flow when the valve is fully
opened assuming that its resistance is negligible
and that f for both pipes is 0.0054. In order to
restrict the flow the valve is then partially closed.
If k for the valve is now 5.6, find the percentage
reduction in flow.
