A falling head permeability test was run on a soil sample 12.3 cm. in diameter and 11.4 cm. long. The head at the start of the test was 93 cm. and falls to 73 cm after 38.2 mins. The diameter of the stand pipe was 1.54 cm. Determine the flow rate (in cm^3/min) through the soil. Use head loss method. Round off to four decimal places.
