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.

What is the difference between PVC and XLPE

What is the difference between PVC and XLPE The structural elements of wire and cable products can be generally divided into four main structural components of wire, insulation, shielding, and sheathing. For power cables, according to different insulating materials, low-voltage power cables are mainly the following two kinds: PVC insulated power cables and XLPE insulated power cables.

Tech Note: Understanding Cable Stress and Failure in High

Cables flex in one or more of the four basic motions illustrated in Figure 1. Each time a cable bends or flexes, its copper conductors and shields are stressed. Copper has poor resistance to repeated stressing, even if the stress is kept below its ultimate yield point of 15 percent elongation.
