FireOps Calc is a fast, accurate, firefighter-designed pump calculator built for real-world fireground operations and training. Whether you’re a line firefighter, pump operator/engineer, officer, or student preparing for promotion, FireOps Calc delivers reliable pump pressures using your department’s actual hose and nozzle setup.

FireOps Calc removes the guesswork from fireground hydraulics. Quickly calculate friction loss, nozzle pressure, total pump pressure (PDP), elevation change, and appliance loss with clear results and detailed breakdowns. Every calculation dynamically adapts to the hoses, nozzles, and appliances selected in Department Setup, including custom entries.

? Department Setup

Customize the app to match your department’s exact equipment:

• Hoses (diameter, length, type)
• Nozzles (fog, smooth bore, specialty, master stream, and custom)
• Appliances and standpipe settings
• Custom lines and saved presets

Your selections automatically populate the pump calculator for accurate, real-world results every time.

? Pump Pressure Calculator

Instantly calculate pump pressures for:

• Preconnects and handlines
• Multi-line operations
• Standpipe and high-rise fires
• Master streams and specialty lines

Includes elevation loss/gain, appliance loss, smooth bore nozzle pressure, fog nozzle pressure, and friction loss based on your hose selections.

? Water Supply Tools

Plan and manage complex water supply operations with tools for:

• Relay pumping (engine spacing and pressures)
• Tender shuttle fill, dump, and cycle time
• Drafting calculations
• Hydrant and supply line support

? Practice Mode

Build confidence and speed with scenario-based pump practice questions. Perfect for engineers, students, and anyone looking to sharpen fire pump and hydraulics skills.
