Thanks again for the reply Canuck ... I finally figured it out ... closer scrutiny of fig. 6-10 helped ... also found an easier-to-follow example in the front of the '83 "Industrial Ventilation" ... anyhoo, the Static Pressure of the hood (SPh) = velocity pressure of the duct (VPd) + the entry...
Hi fellow Canuck (I'm in Nfld.) ... I have a 1983 copy of that very book here on my desk ... fig 6-10 shows factors for hood entry losses, but am having trouble determining the total loss for the described fitting unfortunately ...
Thanks quark ... forgot to mention that in the system we are tryingto design, we want a carrying velocity of 4000fpm ... which corresponds to a 4" dia. duct @ 350CFM.
Will check out the McQuay software.
Have a nice day!

Hi!
Am currently struggling with a calculating the static pressure loss thru a dust collection fitting ... none of the books I am referencing give a clear step-by-step procedure.
The fitting is a "Tapered Hood" type approx 8"x4" (32 sq. in.) inlet with a shallow transition to a 4" (12.6 sq...
