The image above represents emitter discharge.
To compute for emitter discharge, three essential parameters are needed and these parameters are Constant for Each Emitter (K), Pressure Head (h) and Emitter Discharge Exponent (x).
The formula for calculating emitter discharge:
q = Khx
q = Emitter Discharge
K = Constant for Each Emitter
h = Pressure Head
x = Emitter Discharge Exponent
Let’s solve an example;
Find the emitter discharge when the constant for each emitter is 21, the pressure head is 12 and the emitter discharge exponent is 2.
This implies that;
K = Constant for Each Emitter = 21
h = Pressure Head = 12
x = Emitter Discharge Exponent = 2
q = Khx
q = (21)(12)2
q = (21)(144)
q = 3024
Therefore, the emitter discharge is 3024.
