An experimental filter consists of a 2-m depth of uniform sand with a diameter of 0.85 mm and a shape factor of 0.7. The porosity of the bed is 0.35 and the specific gravity of the sand is 2.65. Determine the head (in meters) to maintain a flow of water through the bed at a flow rate of 10 m/h. The water temperature is 15°C.
