A permeability test was run on a cylindrical soil sample with a length of 175 mm, and a diameter of 75 mm. After 90 seconds, discharge was 300 cm3 under constant head of 41 cm. The sample had a dry mass of 850 g and its ?s was 2.60 g/cm3.
Calculate
(a) the coefficient of permeability,
(b) the discharge velocity, and
(c) the seepage velocity during the test.
(d) What was the probable type of the soil tested?
A sample of 10 television tubes produced by a company showed a mean lifetime of 1200 hours and a standard deviation of 100 hours. Estimate (a) the mean, (b) the standard deviation of the population of all television tubes produced by this company.
