How do you calculate FL(Friction Loss) for multiple lines of same size? - ans -Just
figure out PSI for one line and same goes for wye and siamese operations you just
figure out one side but don't forget to make sure you figure out correct GPM for
the line you are calculating FL for.
How do you calculate FL (Friction Loss) for Multiple lines that are unequal size? -
ans -Divide the Total GPM by number of lines and figure out FL(Friction Loss) for
each line. Add all the FL for each line up and divide by the number of lines this
number will be the FL per 100'. Then take the FL and multiply by number of lines.
