The H-Factor

An update to HydraCALC which contains the ability to printout hydraulics conforming to NFPA 2007 is now available for download on our website. As always – when you update your HydraCALC, you must update your HydraVIEW.

Set up your Info Sheet under View->Info Sheet and choose NFPA 2007. Also choose NFPA 2007 when you print it out under the items Info Sheet, Press / Flow Summary and Calculation Sheets. Those screens and the new printouts are below. Please note that the new standard does not give a provsion to include velocity pressure. This means that the 2007 printouts will not be available if you do a velocity calc. This will change if NFPA creates such a provision.
