A clay sample is 2.5 cm high and has a diameter of 6.5 cm. It is placed in an oedometer with a variable- head permeameter. The water percolation through the sample is measured in a standpipe whose inner diameter is 1.7 mm. The tube is graduated in centimeters from the top to the bottom. The top graduation is zero and is located 35 cm above the base of the oedometer. The overflow in the oedometer is 3 cm above its base. At the start of the test, the water level in the tube is at zero; 6 mins and 35 sees later, the water level has dropped to graduation 2. What is the coefficient of permeability of the clay in cm/s?
