FireOps CalcFire pump calculation how-to guides.
Useful, practical explanations for firefighters, engineers, pump operators, driver/operator students, and instructors. Each guide explains the math, shows a worked example, and links back to the FireOps Calc web calculator.
Start with a calculation you want to teach or review.
These are written as quick station-training references. They are not a replacement for your department SOPs, manufacturer data, or instructor direction.
The Hand Method for Pump Calculations
Use one hand to remember pump discharge pressure: nozzle pressure, friction loss, elevation, appliance loss, and PDP.
🚒How-to guideHow to Calculate Pump Discharge Pressure
Learn the basic pump pressure formula firefighters use: friction loss + nozzle pressure + elevation + appliance loss.
📏How-to guideHow to Calculate Fire Hose Friction Loss
Use hose size, length, GPM, and C-value to estimate fire hose friction loss.
🔥How-to guideHow to Pump a 1¾ Inch Attack Line
A practical 1¾ inch handline pump pressure example using hose length, GPM, and nozzle pressure.
💧How-to guideHow to Pump a 2½ Inch Attack Line
Calculate pump pressure for a 2½ inch handline using GPM, hose length, nozzle pressure, and friction loss.
🔀How-to guideHow to Calculate Pump Pressure for a Wye Operation
Learn how to calculate pump pressure when one supply line feeds a wye and two attack lines.
🏢How-to guideHow to Calculate Standpipe Pump Pressure
A practical standpipe pump pressure process for training and driver/operator review.
🔁How-to guideHow to Calculate Relay Pumping Distance Between Engines
Use total relay distance and number of engines to estimate spacing and per-section pump pressure.
🔗How-to guideHow to Calculate Two Supply Lines Feeding One Engine
Calculate water supply flow when two hose lines feed one receiving engine or appliance.
🚚How-to guideHow to Estimate Tender Shuttle GPM
Estimate usable water shuttle flow from tank size, fill time, dump time, travel time, and number of tenders.
🎯How-to guideSmooth Bore vs Fog Nozzle Pump Pressure
Understand how nozzle pressure affects final pump discharge pressure for smooth bore and fog nozzle packages.
How to use these pages
Open a guide, review the formula, walk through the example, then use the calculator to change hose length, flow, nozzle pressure, elevation, or appliance loss.
Good for instructors
Use the examples as quick warm-up problems, driver/operator practice, company drills, or pre-class reading before hands-on pump training.
