IMPORTANT: Hydraulics and nozzle-pressure results are educational estimates, not approved fireground pump settings. Verify actual equipment, hose test data, department procedures and operating limits. Medication conversions do not provide clinical dosing instructions.

FIRE HYDRAULICS / TARGET-FLOW PUMP WORKSHEETREFERENCE ESTIMATE · NOT A PUMP SETTING
One straight, unbranched hose line only: Enter the desired GPM at the nozzle, hose size and hose length. Then identify your nozzle and its pressure/flow specifications to estimate pump discharge pressure (PDP). Switch to hose friction loss only when that is all you need.
ADVANCED · HOSE COEFFICIENT (C) & VERIFIED HOSE DATA
Most users can skip this section for a training-only reference estimate. The selected hose uses an example C, which may differ from your actual hose. For operational planning, verify the coefficient against department hose tests or manufacturer information.
What is C? C is the hose's friction-loss coefficient, a number representing how much pressure that particular hose loses as water flows. It matters because a different C changes the calculated pressure loss. Hose diameter, lining, construction and condition can change the actual value.
Don't know C? Ask your department or hose manufacturer for a tested coefficient. For classroom practice, FIRELINE can use an example coefficient based on hose size, but that is not a verified fireground value.
Example coefficient selected from hose size. Verify your actual hose before operational use.
Flow matters: FIRELINE checks your requested GPM against the actual nozzle tip/selected GPM. It uses the resulting nozzle flow when calculating friction loss. There is no universal 165 PSI pump setting for 200 GPM through 400 feet of 1¾-inch hose.
Coefficient reminder: Hose-size defaults are examples only. The actual hose loss may differ. Open Advanced to enter verified hose data.

Choose the actual nozzle rating and confirm verification before a PDP is calculated.
Select a nozzle type. Smooth-bore handline/master references are 50/80 psi, and the pressure field remains editable for a different department-verified value. Selectable/automatic nozzles require their manufacturer-rated flow and pressure.
NOZZLE TARGET: UNKNOWNNOZZLE FLOW: UNKNOWNNozzle data not yet supplied.
PUMP OPERATOR WORKSHEET: Identify the nozzle type and its flow setting or tip size. Verify nozzle pressure against department or manufacturer specifications. The nozzle-rated pressure field is directly above. Enter elevation and appliance losses below when known. Unknown values remain clearly flagged and a complete PDP will not be shown.
PUMP DISCHARGE / TRAINING ONLYNOT A FIELD PUMP SETTING
Optional: leave elevation, nozzle pressure, or appliance loss blank if unknown. FIRELINE displays only known components and explicitly marks the result INCOMPLETE. A full training PDP is shown only when every component is supplied. Elevation correction = ±0.434 psi per foot.
REFERENCE WORKSHEET · Equipment data not yet confirmed.
A calculated estimate is not a validated pump setting. The worksheet does NOT confirm water-supply capacity, nozzle reaction/control, apparatus discharge limits or multi-line hydraulics. Use authorized department pump tables, apparatus limits, hose test data and nozzle manufacturer specifications before fireground operations.

NOZZLE SETTING: UNKNOWN
Enter the hose flow, length and coefficient to see the calculated hose friction loss. This is not a pump setting.
Example: 150 GPM through 200 feet of 1¾-inch hose using C = 15.5 gives 69.75 psi estimated loss. This is not the pump discharge pressure.
FL = C × (GPM/100)² × (Length/100). Generic coefficients are starting estimates, not manufacturer certifications. Use verified hose test data. Excludes elevation, nozzle pressure, and appliance losses.
SAFETY GATE: Reference unit conversions only. No drug-specific dosing, dose-to-volume, infusion-rate, oxygen administration, or clinical decision calculations. Hydraulic and pump discharge estimates are educational references only, not operational pump instructions. Independently verify all operational values using authorized procedures and equipment.
