Water mist systems are becoming increasingly more popular as an alternative to traditional fire sprinkler systems but like any new technology we need to carefully understand its benefits and limitations and this is also true when we look at hydraulic calculations for such systems.
The best guidance for hydraulic calculations with use with low, intermediate and high pressure systems can be found in NFPA 750 which provides detailed guidance on velocity limitations, use of additives and the pressure loss formula which must be used. For many systems the traditional Hazen Williams pressure loss formula will not be adequate and should be changed to the more reliable Darcy Weisbach
You have always been able to switch between these two pressure loss formulas in FHC but with the increased use of water mist systems and the complexities of knowing which pressure loss formula to use Canute has updated its technical data sheet TDS #1 'Using FHC for water mist calculations'. This document explains NFPA 750 methodology for water mist hydraulic calculations and which pressure loss formula is suitable for the various types of system, it also shows how you can use this information within FHC software to your best advantage.
To help Canute FHC customers get the very best out of using our FHC - hydraulic calculation software we regularly hold webinars on different aspects of our FHC software, principles of hydraulic calculation for fire protection systems and other subjects related to fire protection.
Our next webinar will be held on 2 April, 2015 at 14:00 hours GMT/UTC and is subject is 'Basic principles of FHC' and will cover the fundamentals of using the FHC software is suitable for the first-time user or those wishing to have a quick refresher about some of its basic concepts. Once you are registered on the webinar you will receive an email from us normally the day before the webinar is to take place with all the information you require to participate. This will consist of a web link which will enable you to connect your computer to the webinar session so you will need a laptop or desktop computer with an Internet connection and speakers.
Canute offer these webinars free of charge as part of our support program for existing Canute FHC customers to enable them to get the best about our software however if you have any particular queries please do not hesitate to contact our support team who will will be pleased to help you.

After a year's work BSI has now issued BS 9251(fire sprinkler systems for domestic and residential occupancies – code of practice) for public comment. The Revised standard is considerably changed from the 2005 version and provides more clarification and insight. One of the major changes is that it has removed 'residential' and 'domestic' classifications in favour of type 1, type 2 and type 3 classifications this is undoubtedly a move in the right direction and will be give much more flexibility.
We have just booked for the London fire sprinkler international 2014 conference.
The two-day program is filled with international speakers from around Europe and the USA. Will provide a great opportunity for delegates to keep abreast of the latest developments and standards in fire sprinkler technology in an ever-changing market. It will also be interesting to see how other countries have developed the market and persuaded legislators of the benefits fire sprinkler systems.
The conference is to be held on the 20th and 21st May 2014 at the Trinity Suite, Grangetown bridge hotel, London. You can find out more information and booking information at the conferences website London fire sprinkler international 2014
The Conference program details the full programme of the conference over the two days
Canute look forward to attending the conference and meeting many of our customers.
INSAT standards organization has published a draft standard pr INSTA 900-3 : 2013(E) - (Residential sprinkler systems — Part 3: Watermist systems equivalent to residential sprinklers). This standard continues the work of the Nordic group to produce a series of standards for Residential Sprinkler System and part three coves the test methods for alternative water base fire fighting systems as required in INSTA 900-1 and 2.
The INSTA 900-3 standard allows equivalency to be established using any of three different fire test protocols: UL 1626, FM 2030 or DD 8458. We are informed that it will not be long before DD 8458 to be converted into a full British Standard.
Canute LLP are pleased to announce that it has been accepted as a member of the European Fire Sprinkler Network. The EFSN is a coalition of fire safety, political and other relevant communities which encourages the use of fire sprinklers to save lives and protect property and the environment.
John Moore, partner at Canute LLP said "We are very pleased to be able to support the work of the EFSN and to be part of the wider fire sprinkler community in Europe. It's by working together that we can both educate and expand the market and help reduce fire deaths; helping to make the world a safer place"
The European Fire Sprinkler Network collects and distributes accurate information about fire losses and fire sprinklers, and connects and supports those who believe that fitting fire sprinklers is essential to help Europe save itself from fire.
Working with its members, the Network establishes contacts with those responsible for fire safety at a European level, so as to inform and educate them about the benefits of fire sprinklers.
