(OP)
What effect does piping have on a fan/blower's static pressure. The unit I'm working on requires an air pressure of 40 inches of water gauge. The fan providing the air has an 8" diameter pipe at its discharge which proceeds to a 2' header and then to a 5" diameter pipe to a 2" line into the unit. I have not have any experience with industrial fans. Thanks.

Also, unlike water, the velocity head is significant in blower/fan applications and cannot be ignored in
duct / blower sizing calculations, etc.
