Flow Calculations
Flow of Liquefied and Gaseous Agents
Thousands of piping systems have been designed using programs developed by GSI. Literally thousands of discharge tests, both in the laboratory and in actual field installations, confirm the accuracy of the flow calculations.
Computer programs for Carbon Dioxide, Halon 1301, Halon 1211, HFC227ea (FM200), HFC-23 (FE13), HFC-125 (FE-25), FK-5-1-12 (NOVEC); inert gas clean agents IG541 (Inergen), IG-55 (Argonite), and IG-100 (Nitrogen); wet chemical extinguishants, dry chemical (powder), and water.
The theory upon which GSI's computerized calculations is based has been published in various NFPA Standards and presented in numerous public forums. For a copy of a selected presentation given by GSI's Tom Wysocki, contact Mr. Wysocki by e-mail or download file using the link below.
Programs have been listed and approved by nationally recognized testing laboratories in the United States, United Kingdom, Japan, Australia, Korea and Canada.
