WebBuckingham Pi Theorem (# of P terms) = (# of variables) – (# of reference dimensions) • P terms are dimensionless terms. • Reference dimensions are the dimensions required to describe the variables in the equation. These are usually the same as basic dimensions, but in some cases can be different. For example, let A, WebBeck, Nuss and Dunn proposed that the equation for the flow of a Bingham plastic fluid in a cylindrical pipe could be applied to an annulus if the pipe radius were …
