Study on the Fitting Equations of Discharge Coefficient for Entrance Flowmeters

摘要

A general form of discharge coefficient for entrance flowmeters, c=c_(0)-c_(1) Re~(c_(2)) is suggested and used to fit the calibrating data successfully. The main problem concerns to solve a set of nonlinear sequations, which is solved by a series of solutions of linear equations. This fitting equations are valuable and suitable for some other flowmeters.
