This technique is used to measure the discharge or flow for tube well or pipe sections. It is very simple and easy method to measure. It has basic three essential requirements for discharge determination.
Inside diameter of the pipe
Measurement of X-coordinate of flow ( horizontal distance measured from the end of the pipe)
Measurement of Y-coordinate of flow (vertical distance measured down from the horizontal point to the top of the water jet.)
Case A: for full flowing Pipe
Q = 0.0174 D X / Y
Where
Q = lps (liter per second)
D = Inside diameter of the pipe (in centimeter)
X = X-coordinate (cm)
Y = Y-coordinate (cm)
