Reverse Flow

Fire Hydraulics

Hydraulic workspace, defaults, references, and operational tools for Reverse Flow.

Field Calculators Quick field math for flow, reaction, tank time, and hose coefficient checks.
Smoothbore Flow Calculate flow from tip diameter and pressure. Open Nozzle Reaction Calculate smoothbore or fog nozzle reaction. Open Tank Time Estimate onboard water duration at a known flow. Open Water Shuttle Estimator Estimate sustained shuttle flow from one or more tenders. Open Water Velocity Calculate water velocity from hose ID and flow. Open Estimated Remaining Supply Estimate additional hydrant supply at a selected residual pressure. Open Coefficient Calculator Verify hose friction loss coefficient from a 100' test. Open Friction Loss / 100' Calculate hose friction loss per 100' at a known flow. Open
Hose Management User-owned hose profiles and default hose names.
My Hose Profiles Department, custom, and manufacturer-derived hose profiles for default hose naming.

My Hose Profiles contains user-created hose profiles. Manufacturer reference data stays read-only under References, and any manufacturer-derived profile here is a local copy you can edit for your department.

Create Hose Profile Add a department-specific or custom hose profile to My Hose Profiles.
Friction Loss Chart Generator Generate a friction loss chart from your current default hose coefficients. Open
Equipment Defaults Configure the default equipment and calculation values used throughout Reverse Flow.
Default Hose Selections Hose profile names selected from My Hose Profiles.
Default Hose Coefficients Set the default friction loss coefficient for each hose size.
Equipment Visibility Customize which equipment appears in selection lists throughout Reverse Flow.
Hose Sizes Choose which hose sizes appear throughout Reverse Flow.
Smoothbore Tips Choose which smoothbore tips appear throughout Reverse Flow.
