WebNov 16, 2004 · Assuming that the air flows through the 54”x36” duct and based on experience I would normally calculate: 1. the loss in the 54”x36” as a straight duct run (with the Branch Airflow). 2. the Loss Coefficient for a Mitered Elbow with Diverging Flow at the elbow. 3. the loss in the 96”x36” as a straight duct run (with the Total Airflow). One-dimensional (1-D) flow refers to flow of gas through a duct or channel in which the flow parameters are assumed to change significantly along only one spatial dimension, namely, the duct length. In analysing the 1-D channel flow, a number of assumptions are made: • Ratio of duct length to width (L/D) is ≤ about 5 (in order to neglect friction and h…
