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.

Governing equation

PDP = NP + C (\frac{Q}{100})^{2} \frac{L}{100} + 0.434 h = 100 + 25 + 0 = 125 psi

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