Run your first scenario: fire flow capacity
Use case
Imagine you’re a network operator and you need to confirm how much fire flow you can extract from a hydrant—without compromising pressure in the system. In this step-by-step exercise, we’ll show you how to do that using Qatium’s platform.
You’ll work with the demo network, Magnetic Island, and focus on hydrant H_25760558 located along Pietro Ct in Horseshoe Bay DMA. The goal? Check the maximum flow (l/s) you can extract at peak hour (07:00), while ensuring that pressures stay above 20 meters.
Step-by-step guide
Follow the steps below to run your own fire flow simulation in Qatium:
- Open Magnetic Island in your personal workspace
- Find the hydrant H_25760558 using the search bar. Remember, you can also search for address!
- Move the timeline to 07:00 am.
- Open the Demand Spike panel
. Use the scenario tools located on the right side of your screen.
- Select the hydrant by clicking on it.
- Increase flow rate until pressure is at or near 20 m. You can use the slider or directly type the number into the text box.
- Check the maximum flow that can be extracted from the hydrant. You should be seeing around 38.5 l/s.
- Activate the Pressures panel
to check the pressure in the zone.
- Switch to My network in the Network versions panel
to see pressure difference, then return to My scenario.
- Go to the minimum pressure using the hexagons in the pressure panel. You should be getting a minimum pressure of around 20.3 m.
- Use the range filter to confirm there are no customers affected with pressures under 20 m.
That's it!
You’ve successfully completed a fire flow analysis with Qatium, and now you are ready to perform your own scenarios.
