Ground Water Flow in Pressure Well

?

Formula

The Ground water flow in pressure well in equilibrium conditions is as follows:
The discharge formula in pressure well is as given below;

Q=(2.72*k*m(H-h))/(log(R/r))

Where,

Q = Discharge in cubic meter per day,

k = Permeability meter/day,

m = Depth of confined aquifer in meters,

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,
