Hanan Guest Posts: n/a	Hi everyone, I need to calculate the pressure drop for an air duct with 2 or more bends at various locations of interest. The flow is turbulent with one inlet and one outlet. From what I know, there are two way to approach this problem: (1) to solve for the volume- (or area-) weighted average of total pressure, or (2) to solve for the mass-weighted average of total pressure at the plane of interest. Which pressure drop calculation would you recommend and why? Are there better ways to approach this problem? Thanx, Hanan.
