BOSfluids 8.0 Support for NFPA Analyses

While BOSfluids has provided support for the analysis of fire water systems for some time, it lacked support for some if the calculation rules specified in the NFPA 13 and NFPA 15 standards. BOSfluids 8.0 rectifies this situation by providing a new NFPA analysis type that complies with those calculation rules. This means that the pressure losses are calculated with the Hazen-Williams equation and the equivalent pipe lengths associated with different types of fittings. An NFPA analysis yields the flow rates and pressure distribution in a piping system, the minimum supply pressure required to obtain a specified goal, and a report that complies with the NFPA 13/15 standard.
BOSfluids, NFPA Analysis
The addition of the NFPA analysis type makes BOSfluids 8.0 a comprehensive tool for the assessment and analysis of fire water systems from different points of view. You can start with an NFPA analysis to determine the supply pressure that is needed to obtain the minimum flow rate through the most remote or all sprinklers in a system. You can then go one step further and perform a Fire Water Coverage analysis in order to assess whether all objects of interest are sufficiently wetted. This is particularly useful when dealing with (offshore) industrial systems in which those objects have non-trivial geometries.
BOSfluids, fire water coverage.

NFPA and Fire Water Coverage analyses are essentially steady state analyses. While they tell you something about the performance of a fire water system in operation, they do not tell you anything about transient phenomena that can lead to significant damage and failures when the system is activated. Those transient phenomena can lead to severe pressure surges and unbalanced loads, in particular when dry fire water systems that are rapidly flooded with water. By performing a Flood & Drain analysis you can assess the expected pressure surges and unbalanced loads in advance so that you can avoid costly repairs to a damaged system.

With BOSfluids you can not only perform these different types of analysis within a single application, you also can perform them with a single piping model. In this way you save time and reduce the scope for modeling/conversion errors.
