A. directly proportional to time and inversely proportional to drainage path
B. directly proportional to time and inversely proportional to square of drainage path
C. directly proportional to drainage path and inversely proportional to time
D. directly proportional to square of drainage path and inversely proportional to time
q= khNf/Nd
Thanks Gourab
Thanks gourab brother
Discharge per unit length=KhNf/Nd
So, q=0.03 x 10^-3 x 30x 5 /25 m³/sec
=0.00018 m³/sec
Where, K=coefficient of permeability
h=head available
Nf=number of flow channel
Nd=number of potential drop
Please give me solution of above question
