as we know to draw the system curve of a piping system we have to change the value of
Q total and get a head for each value we put in the following equation : H=Hstatic +Kq^2
where K is the sum of major and minor losses.
what if we have a piping system that have many branches "tree -system" , how can we plot the system curve then ?
if we take the longest run and apply the above equation the change in Q all along the pipe will interrupt our calculation because the foumula will look like the following:
H=hst +K1Q1+K2Q2+K3Q3 ...
BUT usuallly for a single pipe system we have 1 Q all along the pipe which is the total Q , what do we do in the case of branched system ?
