Question

The coefficient of permeability of a soil sample 6 cm in height & 50 cm^2 in cross-sectional area, and if 430 ml water passed in 10 minutes under an head of 40 cm is

Answer 1

Answer:

Explanation:

k=ql/Ah (q is discharge in cm^3/sec, l is length , A is area, H is height)

discharge=  (500ml = 500cm^3 ,15 min= 15*60= 900) 500/900

lenght=  40cm

area 50*2= 100 cm

height= 6 cm

500*40/900*100*6

0.045
