THE diaphragm-cell technique, first introduced by Northrop and Anson1, has been widely used as an experimental method of utilizing Fick's first law to obtain diffusion coefficient s in liquids . The. The RS measurement using the ultrasonic method is based on the acoustoelasticity law, which states that the Time-of-Flight (ToF) of an ultrasonic wave is affected by the stress field. 2016. 6. 1. · The diffusion coefficient is a variable present in the operations of mass transfer, since it is part of many correlations. For this reason it is necessary to know its value or to determine it. 2004. 7. 1. · Average value of diffusion coefficient (D avg) for a particular C avg was obtained by calculating the diffusion coefficients for different time intervals.

Measurements of diffusion coefficients in liquids H.A. Claessens, J.H.M. van den Berg Research output : Contribution to journal › Article › Academic › peer-review. 1. DIFFUSION MRI THROUGH A BIRD’S EYE One of the most astonishing things about the world in which we live is that there seems to be interesting physics at all scales. 〈 〉 To do physics amid this remarkable richness, it is convenient to be able to isolate a set of phenomena from all the rest, so that we can describe it without having to understand everything. Diffusion coefficients in liquids are about ten thousand times slower than those in dilute gases.
