Air flow resistance through variable height columns of wood chips and sawdust was evaluated by means of the pressure drop across an orifice plate. Input pressure to the bottom of the column was controlled by means of a sliding gate valve or damper on the supply fan air intake. Flow per unit of cross section plotted against input pressure per unit of bed depth yielded the expected straight line response on a log-log plot. The response for chips was similar in both actual value and slope to the flow characteristics of similar size products such as bean pods. The flow through sawdust was similar to the flow through fescue seed. Coefficients for the classical airflow equation were evaluated from the data. 7 references.
