Studies on Measuring Method of Respiration Rates of Fruits and Vegetables (Part 3)

—Application in a Flowing System for an Unsteady State—

Abstract

When a flowing system using the conventional formula was applied to an unsteady state despite the assumption of a steady state, the occurrence of errors was observed. Because a steady state cannot always be assumed, the application of the flowing system to an unsteady state was considered using the modified formula obtained in a previous study. The range of inflow rate that could be used and the accuracy required for gaseous concentration measurement were determined using the defined outflow concentration range. The onset of measurement was determined using the ratio of quantity of dry gas in a respiratory chamber to the inflow rate. Thus, the flowing system using the modified formula can be applied to an unsteady state.
