FireOps CalcStandpipe calculation pieces
A standpipe calculation usually includes the pressure needed at the standpipe outlet, hose friction loss from the outlet to the nozzle, nozzle pressure, elevation, and any appliance loss.
Different departments may use different target outlet pressures or high-rise SOPs, so FireOps Calc should make the assumptions visible.
Common inputs
Floors up or down
Elevation matters because pressure changes as water moves vertically.
Hose inside building
Attack hose from the standpipe outlet to the fire area still creates friction loss.
Nozzle and flow
Smooth bore, fog, and special nozzles may require different pressure and flow values.
Worked example concept
| Item | Example |
|---|---|
| Standpipe outlet target | 100 PSI |
| Interior hose | 150 ft of 2½" |
| Nozzle | Smooth bore or fog nozzle based on department setup |
| Elevation | Based on floor height and connection location |
| Final answer | Show PDP plus the full math breakdown |
Training value
Standpipe pump pressure is a good training topic because students have to think beyond a simple preconnect. A good calculator should show how each input changes the result.
FAQ
Why is standpipe pressure different from a normal handline?
Standpipe operations may include building piping, elevation, interior hose, outlet targets, and department high-rise procedures.
Should the pump operator follow the calculator or SOP?
Follow department SOPs and instructor direction. FireOps Calc is a training and quick-reference tool.
Can this help with fire academy training?
Yes. Standpipe pages and scenarios can support driver/operator, engineer, and fire academy hydraulics training.
