A falling head permeability test was run on a soil sample 11.4 cm. in diameter and 12.9 cm. long. The head at the start of the test was 91 cm. and falls to 74 cm after 34.5 mins. The diameter of the stand pipe was 1.04 cm. Determine the flow rate (in cm^3/min) through the soil. Use head loss method.
