Study 1. Properties of working fluids, coolants and structural materials for thermal engineering calculations

ValeryOchkov
24-Ruby IV

Study 1. Properties of working fluids, coolants and structural materials for thermal engineering calculations

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.

I have used the template (see Fig.1.13) and have create 3 function with properties of Ethylene Glycol water solution.

See too http://www.mrc-eng.com/Downloads/Brine%20Properties.pdf

And more... See please the attach

And more... Can we correct ORIGIN DATA
