PDP Builder

Step 1

Target nozzle pressure

Target nozzle pressure (psi)

Step 2

Target flow (GPM)

Step 3

Friction loss (hose)

Hose length (ft)

Hose diameter (in)

Friction-loss coefficient C (table value for 1.75″: 15.5)0.05 to 60 (C — table 15.5)

Flow-tested your hose? Enter the measured C — modern low-friction jackets often test well below the textbook table. Leave the table value to use the training default.

Number of lines

Step 4

Elevation gain/loss

Elevation input

Elevation gain/loss (ft)

Negative values reduce PDP (nozzle below pump level).

Step 5

Appliance friction loss

Appliance

Enter values above to see the result.

Build the same target on the pump panel: set your line up and throttle until the master discharge gauge hits your PDP. Open the pump panel
