Friction loss uses the fireground formula FL = C·(Q/100)²·(L/100), added to nozzle pressure and elevation head to give the required pump discharge pressure. Coefficients are standard single-line values. Verify against your department's charts.

Reading this result: Friction loss is modest here, so nozzle pressure sets most of the 125-psi discharge the pump must supply.
