Hello, please answer this question and check my answer!

Determine the following: Assume the following dimensions-the manometertube diameter was 3.7 cm. and the height and the diameter of the cylinder of soil were 9 and 10 cm, respectively. The height of the water in the manometer was 1.03 m above the water lev el in the bucket containing the soil sample. This height reduced by 7 cm over 7 days. B1. What is the coefficient of permeability of the soil in m sec?| a = Area of Burette Stand Pipe A = Area of Specimen /i1=Head at t = 0 /i2=Head at t = final L or 1 = Length of Specimen a = 10.752 cm2

Explanation / Answer

a = pi*(3.7/2)^2 = 10.752 cm^2

A = pi*(10/2)^2 = 78.54 cm^2

l = 9 cm

h1 = 103 cm

h2 = 103 - 7 = 96 cm

t = 7*24*60*60 = 604800 s

K = 2.303*(10.752*9/78.54*604800) * log (103/96) = 1.434*10^-7 cm/s = 1.434*10^-9 m/s
