A LABORATORY EXPERIMENT ON HOW TO CREATE DIMENSIONLESS CORRELATIONS

摘要

Dimensionless correlations are a prominent feature in the practice of chemical engineering. It is difficult, however, to create a student experiment that will illustrate how they are created. For instance, a pipe flow experiment can be set up where pressure drop is measured as a function of the flow rate. The results can be consistent with the published dimensionless correlation, but the results cannot be called a verification of the correlation unless all the relevant parameters have been varied.
