E-Z Solve syntax

Consequently, this system may be represented by 14 algebraic equations, one for Kp, one for nt, and four each for nt, and pt. These equations, plus the known values for Kp, H2 0 and nC02 0 m y be entered into the E-Z Solve software and solved for x. The values of n(, yh and pt are then calculated based upon the value of x. The E-Z Solve syntax is listed below. 

This latter differential equation, coupled with the algebraic expression relating qout to h, may be solved to determine the fluid height as a function of time. The initial fluid height is 50.93 m, based upon the specified initial fluid volume and tank diameter. This serves as the initial condition to be used for the integration. The E-Z Solve syntax is ... 

In E-Z Solve, a separate equation entry is required for each data pair. The software then determines the values of m and b which minimize the sum of squared residuals (SSR). The E-Z Solve syntax is shown below. 

The riant and fj-ateeq functions must be used for cases in which an analytical solution to the governing equation is not available, rkint is a standalone Runge-Kutta integration routine which may be imported and used for other problems of this type. The function f-ruteeq contains the expression to be integrated it may be edited as required for the problem at hand. The form of f-ruteeq is shown in the E-Z Solve Syntax, above. 

In this appendix, we illustrate how E-Z Solve may be used for each of these types of problems. We expand on the basic features of E-Z Solve described in the Help and Help/tutorial menus in the software. The file Appendix.msp in the E-Z Solve software contains the equations used to solve examples D-l to D-4 which follow. The main elements of the syntax are also printed within this appendix.
