Hi, I'm an Air Balancer, and am trying to develop a more accurate way to estimate a target airflow for each vent as I adjust the damper for it.
I assume that airflow, after a damper adjustment, distributes itself proportionately. Here's the problem I'm trying to solve:
A + B + C = D These are my design airflows for each vent, with D the total design airflow.
E + F + G = H These are my measured airflows. H will be close to, but not D.
J + K + L = H These are my targeted (but not final) airflows, after adjusting the damper for K.
My goal is to adjust the flow for K such that K's proportion to design A is identical to J's proportion to design B.
Therefore:
J/A = K/B
Solve for K in terms of A, B, D, E, F, & H. ( and D, if needed).
Many thanks for your assistance,
