185Graph

185Graph is a Windows application that can generate graphs according to the fire sprinkler hydraulic calculation in relationship to water supply demand. It lets you set the flow and pressure limits, calculate friction loss, analyze the gradient, and more.

The interface consists of a full-screen window that shows an empty graph by default, so you can start tinkering with settings to get the desired results.

The water supply demand details that can be put together are the density, area, flow, pressure and elevation. You can define grid properties when it comes to the number of branch lines and heads per line, head and line spacing, feed location, elevation, roof slope, and many others.

Other parameters pertain to the design, pipe and feed main data, along with demand and loss detail. Multi-demand water supply information can be established too. As far as supply information is concerned, you can indicate the type (data points, fire or booster pump), hose flow, loss, and elevation. Lastly, you can point out details for the pump rating.

Additional tools of 185Graph permit you to calculate the friction loss or C factor, as well as the orifice discharge by specifying the pitor, orifice and coefficient to generate the flow. Plus, you can perform a gradient analysis.

The graph can be immediately plotted and you can save the project to file to resume it later. Although 185Graph does not integrate an option for exporting the graph to an image, it can be copied to the Clipboard and pasted into a photo editor, or directly printed. Any other calculations can be printed too. Undoing and redoing actions is possible, so you can correct any mistakes.

We have not come across any stability issues in our tests, thanks to the fact that 185Graph did not hang, crash or pop up error messages. It leaves a small footprint on computer performance, so it shouldn't interfere with the runtime of other active processes.

Considering its wide range of settings and calculators, 185Graph should satisfy the requirements of most users looking for an app to put together and export graphs based on the fire sprinkler hydraulic calculation relative to the water supply demand.
