WebVersion: 1.0. Syntax: CStr (Expression) The CStr function converts an expression into a variant of subtype String. If the expression is Boolean, the output is a string containing either true or false. If the expression is a Date, the output is a string using the short-date format. If the expression is empty, the output is a zero length string. WebMar 11, 2024 · The following is an application of Euler's method for the CSTR on the change in concentration: C A i = C A ( i − 1) + d C A d t Δ t. This same application can be made to the change in temperature with respect to time: T i = T i − 1 + d T d t Δ t. Assuming that all values in the ODE's remain constant except for and , the new value is then ...
