A cylindrical soil sample, 7.3 cm in diameter and 16.8 cm long, is tested in a Constant Head Permeability Apparatus. A constant head of 75 cm is maintained during the test. After 1 min of testing, a total of 945.7 g of water was collected. The temperature was 200C, and the void ratio (e) of the soil was 0.43. Calculate the "Coefficient of Permeability" in "centimeters per second" (Given, k = (QL)÷(A Δh t)).
