Emitters are devices associated with junctions that model the flow through a nozzle or orifice that discharge to the atmosphere.  With the following equation, q = flow rate, p = pressure, C = discharge coefficient, and > Macro (inline-external-image)

 = pressure exponent.  The emitter tab allows the user to enter the C - coefficient for the selected node.
