Many thanks for all replies. I looked "^" said it meant something different.....so thanks for clarifying. Okay...i looked up values online. 1600(M^3) = 56503.4668 FT^3 1 foot of 8inch tubing is 0.349 cubic feet. Divided. Got: 161901.051002865. That equals= 30.6630miles. So, i guess thats the speed?

Hi doG. Many thanks for reply. Nope, its windtunnel help.... Set up a makeshift wind tunnel to test aerodynamic effect of new roof plug im doing. Was curious as to MPH of test, and how that may change with extra MPH. Extractor didnt have any tubing, other than the outlet: Sorry, i dont understand what "1^3" means.....

Hi everyone. Im hoping someone can tell me speed, in MPH, of airflow from an extractor fan please. The extractor is 8inches (200mm) diameter. Figures says its 1600m3/hr. Any help greatly appreciated.
