Can FluidFlow be used to model Fire Protection Systems?

Yes. FluidFlow includes a proprietary Sprinkler and Fire Hydrant node and includes a comprehensive database of components as standard. Additional sprinklers can be added to the database by either entering a single nominal K value or entering the flow vs pressure loss relationship and additional hydrants can also be added by either entering a single K value or a pressure loss relationship of % open vs Kv/Cv.

Note, when defining either of the above items using a pressure loss relationship, FluidFlow automatically generates the curve-fit.
