This document provides information on how to use FHC successfully for water mist calculation. FHC can be used with NFPA 750 for low, intermediate and high pressure systems. FHC can also be switch between Hazen-Williams and Darcy-Weisbach equations as required.

The FHC program will correctly calculate systems deigned to BS 9251 for both residential and domestic occupancies. However it is important to insure that the information in the TDS #3 is followed.
