The return air damper will remain open until the outside air dampers reach 90% open. Modulate return air dampers from 100% open to fully closed as the outside air dampers modulate from 90% open to fully open. Modulate relief/exhaust fan speed to maintain building static pressure at approximately 0.02” Leave relief/exhaust air dampers fully ...

[DOC File]A VBASIC SPREADSHEET TO CALCULATE DUCT DIAMETER
https://info.5y1.org/return-air-cfm-calculator_1_9c20f4.html
At air flows greater than 15,000 cfm, air velocity in the duct may become excessive and create noise problems. This program does not address this contingency, so at these higher air flows, the user is advised to manually calculate duct diameter based on an acceptable air velocity, rather than relying on the diameter calculated based on equal ...

Now we will change the air flow rate through Section 2 from 3400 CFM to 3000 CFM. We will illustrate how once you know one (CFM, S.P.) point of a system you can use the Fan Laws to calculate the pressure loss for other air flow rates. Section 1. There is no change. P t loss 1 = -1.165” Section 2. Air Flow Rate Q = 3000 CFM

M1602.4 Balanced Return Air. Restricted return air occurs in buildings when returns are located in central zones and closed interior doors impede air flow to the return grill or when ceiling spaces are used as return plenums and fire walls restrict air movement from one portion of the return plenum to another.
