The rectangular duct consequently calls for a lot more metallic for its design, this provides far more excess weight and fees for the design. The larger sized perimeter also suggests much more air will arrive into contact wit the material which provides friction towards the system.

325 kPa. We will appear this up inside our air Houses tables but I like to simply use an online calculator  as its more quickly. So we just drop These figures in and we obtain the density of air becoming 1.2 kg/m3.
