WebTo 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. WebThe online fan power calculation is to calculate the power required for fan to operate for the required airflow and pressure. +91 9302328890 / 9399948021 [email protected] Facebook WebStep 2. Leaf blowers also use centrifugal blower fans. Define the terms in the general centrifugal fan formula and rearrange them to use the formula to solve for the higher air flow: CFM 1/CFM 2 = RPM 1/RPM 2 x (D1/D2)^3 (cubed). The (D1/D2)^3 is 1, since the impeller diameter stays the same, so CFM 2 = CFM 1 x (RPM 2/RPM 1). should a 12 year old take birth control
