1.Determine the maximum saturated depth over a landfill liner using the Richardson and Zhao equation shown on page 127 if leachate collection pipes are spaced 30 ft apart. For the landfill location, the vertical infiltration for a 25-year, 24-hour storm is 13 inches. The hydraulic conductivity of the drainage layer is 0.006 cm/s and the slope of the liner is 1.8%.
2. A gas has a pressure drop of 2 psi along a 1000 ft length of straight pipe. The gas has a density of 0.07 lb/ft3 and the pipe inside diameter is 4.026 inch. Approximately, what is the velocity of the gas as it flows through the pipe? Assume that the Darcy-Weisbach friction factor is 0.02.
