Ground Water Flow in Gravity Well

?

Formula

The flow in gravity well in equilibrium conditions is as follows:
The discharge formula in Gravity well is as given below;

Q=(1.36*k(H^2-h^2))/(log(R/r))

Where,

Q = Discharge in cubic meter per day,

H = Depth of water in well before pumping in meters,

h = Depth of water in well after pumping in meters,

R = Radius of Influence Well in meters,

r = Radius of Well in meters,
