Air Flow, Air Systems, Pressure, and Fan Performance

To balance the system by design we must increase the air flow rate in Section 2 to bring it up to the higher pressure loss of Section 1. To correct the air flow rate for Section 2 use the Fan Laws: Q 2 new = Q 2 old * (P t loss 2 new/ P t loss 2 old)1/2. Q 2 new = 3000 * (1.165/0.93)1/2 = 3357 CFM. Section 3.
