  • A Mathcad Function Set For Solving Thermodynamics Problems
    2006
    Co-Authors: Stephen T. Mcclain
    Abstract:

    A set of Mathcad Functions was constructed to evaluate the thermodynamic properties of steam, R134a, air, and twelve ideal gases. The Functions were created to ease the need for time-consuming interpolation using tabularized thermodynamic data while reinforcing the Functional representation of traditional thermodynamic property tables. A consistent and easily remembered scheme has been adopted for naming the Functions. An example is provided to demonstrate the use of the Functions in an undergraduate applied thermodynamics course. The example seeks the reheat pressure that maximizes the efficiency of a Rankine-reheat power cycle provided fixed boiler and condenser pressures. The example is presented in its entirety in the appendix to demonstrate the report-quality worksheets possible using Mathcad. While the example provided represents a use of the Functions in an undergraduate applied thermodynamics course, the Functions have also been used in an internal combustion engines course and in a turbomachinery course. Survey results from three courses and several student comments are discussed.
