Hello
Does ‘Emitter Coefficient’ relate to Junctions which discharge flow to atmosphere and ‘Dsicharge Coefficient’ relate to elements such as Valves which discharge flow (not to atmosphere, but) to a pressured point?
Both of follow Q=K(P2-P1)^n which p1=0 for Emitter Coefficient.
Am I right?
Sim
Hello Sim,
Yes, emitter coefficients are related for junctions or, more commonly, hydrants. Discharge coefficients are related to valves.
