| Abstract: | The measurement of flow rates of solids in gas–solid flows is a challenging task. Fibrous materials are known to change in character as they flow and, as such, can compound the difficulty of measurement of such flow rates over that of powders and granular materials in the transport condition. The principle of measuring the pressure loss experienced by a gas–solid flow in a straight section of piping was used here to test a metering device for fibrous solid flow which has been shown to work for a wide range of powders and granular materials in our laboratories. The flow rates obtained for the fibrous material had a high degree of reproducibility suggesting the possibility of widespread industrial application of the pressure drop flow-metering device. |
