To balance the system by design increase the air flow rate in Section 1 to bring it up to the higher pressure loss of Section 2. To correct the air flow rate for Section 1 use the Fan Laws: Q 1 new = Q 1 old * (P t loss 1 new/ P t loss 1 old)1/2. Q 1 new = 4000 * (1.192/1.165)1/2 = 4046 cfm. Section 3. Air Flow Rate Q = 3400 cfm + 4046 cfm ...

A liquid is forced through the capillary by imposing a pressure drop. The very small diameter of the tube, the very large length to diameter ratio minimizes entrance and exit effects and ensures a fully developed velocity profile. ... Q= volumetric flow rate, cm3/sec. V= average fluid velocity, cm/s. Use Bird, Steward, and Lightfoot, 1960, p ...

"High Pressure" is a general and non-specific figure. What might be "high pressure" for 1/2" pipe (600psi) may not be "high pressure" for 2" pipe (280psi). There are just too many variables to consider to give a real world number. The fact of the matter is, on a pressurized system, the pump will dictate the flow and pressure as much as the pipe ...

The recommended ventilation rate is 15 to 20 air changes per hour [1, p.4; 2, Table1], which, for a room volume 41 m3, gives a minimum target air flow of 615 m3/h. To keep the mean air velocity in the fan duct below the preferred figure of 8 m/s [2, Table 1], the duct diameter must satisfy:
