Smacna fitting loss coefficients
WebbMumma et al. [9] analyzed the loss pressure coefficients in several ductwork fittings using a commercially-available CFD code, where one duct fitting studied was 90° round elbow. According to those authors the computational determination of duct fitting loss coefficients appears to be a viable alternative WebbSelect the right fitting with required parameter values within the range of ASHRAE specified limits, to aim at fitting having optimum loss coefficient value. Such alternations to …

In this particular circular steel ductwork system the value is 1.3Pa/m (and this may be checked by using figure 4.3 in Guide C). The length of that duct is 5m, and so the pressure drop is 5 x 1.3 = 6.50Pa.
