Specification for FHC Full hydraulic calculation and Analyses Software for fire sprinkler systems

 

Introduction

FHC is a full hydraulic calculation program for use with fire sprinkler systems and other water based fixed fire protection systems to International standards. It has been used successfully with fire sprinkler systems, water spray, ESFR, deluge, drencher, hose reel, hydrant, foam sprinklers, ring mains, foam monitors and water mist systems. 

 

• Complies with international standards such as NFPA, FM and LPC
• Any any type of pipe network can be modelled such as trees, loops, grids or any combination
• Models fire sprinkler systems, deluge, ring mains, hydrant and much more...
• Multiple pipe types
• Specify a global design density or set each head individual
• Automatically finds the most remote head or the four MRH in the case of LPC and EN 12845
• Automatically includes tee and elbows equivalent lengths
• Automatic pipe sizing based on maximum pressure drop or pipe velocity (tree systems only)
• Automatic pipe node numbering
• Calculate source pressure and flow or
• Balance to a water supply curve such as a fire pump or towns main supply
• Can use Hazen-Williams or Darcy-Weisbach pressure loss equations
• Isometric, plan and elevation schematic views of the pipe network
• Easy to read and inclusive reports.

Canute are always please to consider adding new design authority's to the above list for more information please contact Canute Sales department.

 

Pipe networks

FHC can be used for tree, looped and grid systems or in any combination.

 

Design Wizards

QUICK-GRID™ - Helps you to quickly create a grid system given minimal information about a building. TREE PLANTER - Will automatically insert a terminal end fire sprinkler layout at any node in the system.

 

Water Mist Systems

FHC can be used for the hydraulic calculation of water mist systems designed to NFPA 750 and will use the Darcy Weisbach equation for its pressure loss calculations. You can also specify the specific gravity, density (kg/m3) and absolute viscosity (centipoises)
