PLEASE NOTE! This is a fully functional and tested app, but sometimes bugs still find their way into the finished product, so if you have issues with it, PLEASE CONTACT ME at [email protected] before leaving negative comments/feedback, and I will do my best to resolve them. I’m a firefighter on shift just like you are, and work on the apps is done around my shift schedule, so please bear with me. My goal is to give you another useful tool in your toolbox.
OmniFire Friction Loss Calculator is designed to be the fastest fireground friction loss calculator that exists. It was designed BY a firefighter (instead of a programmer sitting in an office somewhere) FOR firefighters, and allows the pump operator to calculate the correct pump discharge pressure for multiple lines in less time than it takes to deploy a hoseline.
With a simple interface that is similar to our sister app OmniMedix , this app allows the fire apparatus driver/operator to calculate friction loss in the most common fire hose diameters, with any length and flow rate using industry standard hoseline coefficients and the universal formula FL=CQ2L.
Also included is a calculator for smooth-bore nozzles which determines the flow rate based for a chosen orifice and user-entered nozzle pressure, which can be added to a given line. To support multi-line operations, OmniFire allows the pump operator to calculate multiple attack or supply lines, and displays the PDP for each line separately on a single screen.
To allow for use in all parts of the world, OmniFire allows the user to toggle between US and metric/SI units. OmniFire automatically adds 25 PSI (175 kPa) for a master stream over 350 GPM (1325 LPM).
Any value may be entered for appliance loss to accommodate appliance-specific friction loss, different numbers of appliances, and variations in department policies for appliance loss. Elevation loss is calculated at the standard 5 psi per 10 feet of elevation.
