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 gamma = pressure exponent. The emitter tab allows the user to enter the C - coefficient for the selected node.
ID - The Emitter (Junction) ID.
FLOW_COEFF - Enter the discharge coefficient (C) here.
Note: You may add rows to this table using the Insert 
or the Append 
icon. You may also delete rows from this table by using the Delete 
icon. This may provide a quick method to assign and/or change flow coefficient values "on the fly".
