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 = Kh^{x}

Where:

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 = Kh^{x}

q = (21)(12)^{2}

q = (21)(144)

q = 3024

Therefore, the **emitter discharge **is **3024.**
