You will learn how to create a function that returns thermophysical properties of working fluids, heat transfer and energy materials using interpolation and smoothing. You will also learn what a cloud function for the thermal calculations is.

Mathcad 15 and Mathcad Prime 3 sheets of the study in attach.

Other way to use in Mathcad 15 one function of dry air density (one figure for 2-d edition of the book).

See please a picture and the sheet in attach.
