Hi folks.
I'm reviewing a contractors hydraulic calculation for a job in which the street main is a dead ended main. The flow test included two hydrants on this main.
I had the contractor submit calculations to the 'residual' or pressure hydrant where as they are insisting they need to calculate the flow hydrant.
I have always assumes the calc. goes to the residual hydrant unless the main is looped in which case calculation to the street main - fire main tie in point is sufficient.
Input? Code reference? Experience?
Much appreciated
