Abstract

The secant method for solving nonlinear equation is used to calculate the unknown parameters of pressure differential devices. It is shown that the important advantages are needing only unique iterative equation without considering different unknows, easily to obtain convergent solutions without to calculate the derivatives which can not be finished for complex nonlinear equation, and yielding high precision solutions. The formulae of initial values and the example for showing the results are presented, the results are excellent.
