A x I
Discharge Required (Q) = 28 -------
R x t
Where Q = Discharge in lps
A = Area in ha
l = Depth of Irrigation in cm
R = Irrigation Interval in days
t = Hours of operation of well per day
Kharif
0.75 x 5 0.25 x 5
Q = 28 ( -------- + ---------- )
20 x 6 24 x 6
= 1.12 lps
Rabi
0.50 x 7.5 0.25 x 7.5 0.25 x 5
Q = 28 (----------- + ------------ + ------------ )
15 x 6 15 x 6 10 x 6
= 2.33 lps say 2.5 lps
Thus the peak discharge required is during Rabi and is estimated at 2.5 lps which should be available from the shallow tubewell.
