Question: A permeameter experiment is being set up to determine the permeability of some very fine sands. The cylindrical samples to be tested will be 30

A permeameter experiment is being set up to determine the permeability of some very fine sands. The cylindrical samples to be tested will be 30 cm long and have a diameter of 10 cm. To improve the accuracy of the experiment, it is proposed that about 50 ml of water be collected before the permeability calculations are performed. If a head difference of 40 cm is used, how much time will each experiment take in minutes? If tracer tests are to be performed later, how much time (on average in hours) will it take a conservative tracer to pass through the sample?
