A note on the algebraic representation of the Preston tube calibration
Abstract
Algebraic expressions are presented for the full range of the Preston tube calibration. Unlike the original formulas presented by Patel, the present expressions are continuous throughout the range of validity with maximum deviation of 1.6% from Patel's results. In addition the variables are cast in natural logarithmic form to facilitate their use on those minicomputers which recognize the BASIC language.
