| Abstract: | To analyzed the existed calculation question in the present chemical engineering teaching,the nonlinear equation’s solution technique for the temperature change of ethanol throttling expansion,as an example,was discussed by using EXCEL.The result indicated that the temperature change followed the equation:ΔT=0.00001T12-0.01300T1+4.55641.The function of goal seek in EXCEL is a simple and no programming operation,which is very suitable for the chemical engineering teaching. |
