Hello,I have a question related to the emitter coefficient of junction.My task is to determine how much will change the flow at the downstream reservoir(which in the program I consider as a junction) if we change pressure breaker elevation for +10m. (we know the material, diameter, length) I tried to use The outflow from an orificeQ=CA sqrt(2gh) ( C=0.62 from libraries)
but watergems uses emitter coefficient at the junction Q = k sqrt (P). is k some kind of conversion factor between head and pressure?Can we write that
k sqrt (P) = CA sqrt(2gh)
please help me to accomplish this equation or give advice on how to solve this kind of task.
