A falling head permeability test sample 9.60 cm in diameter and 100 on a soil mm long. The head at the start of the test was 90 cm. The coefficient of was run permeability of the soil was found to be 5× 10-6 cm/s. The radius of the standpipe was 0.5 cm. a. Compute the rate of flow at the start of the test. b. Compute the potential head drop after 30 minutes. C. Compute the rate of flow after 30 minutes.
