Velocity worksheet

Volume = Velocity (21,190 fpm) x Area (2.1 sqin x 1 sqft/144 sqin - converts sqin to sqft) = 309 cfm @ 28” Since we use feet per second in the flow measurement of ports the formula above the equation becomes: V = 1096.7/60 (18.278) * √¯H/d . V = 353 feet per second (fps) ................
