# Unit 31 Thermodynamics Principles and Practice

Unit 31 Thermo Spec. Thermodynamics. Definition & Facts. Why Can’t We Get to Absolute Zero? The temperature of a substance is a measure of the average kinetic energy of the particles in that substance.

As the average kinetic energy of the particles increases (i.e. they move faster), the temperature of that substance increases. Some of the particles in a very hot substance will be moving slower than some of the particles in a very cold substance, but the average speed of the particles in a hot substance will be faster than the average speed of the particles in a cold substance.

The polytropic process is one in which the pressure-volume relation is given as The exponent n may have any value from minus infinity to plus infinity depending on the process.

Some of the more common values are given below. Here k is the ratio of the specific heat at constant pressure, CP, to specific heat at constant volume, CV. The specific heats will be discussed later. The boundary work done during the polytropic process is found by substituting the pressure volume relation into the boundary work equation. For an ideal gas under going a polytropic process the boundary work is Notice that the results we obtained for an ideal gas undergoing a polytropic process when n = 1, is identical to that for an ideal gas undergoing the isothermal process.

Thermodynamics Graphical Homepage - Urieli - updated 9/10/2013) Engineering Thermodynamics - A Graphical Approach by Israel Urieli (latest update: 4/11/2014) This web resource is intended to be a totally self-contained learning resource in Engineering Thermodynamics, independent of any textbook.

It is designed to be suitable for a two course sequence for Mechanical Engineering majors. It may, however, be used in any format and for any purpose, including self-study. The various unique pedagogical features of this web resource are discussed in Paper AC 2010-47, which was presented at the 2010 ASEE Annual Conference.

In Part 1 we introduce the First and Second Laws of Thermodynamics. In Part 2 we introduce the concept of Exergy to determine theoretical limits of performance of various thermodynamic components and systems, followed by advanced application of steam power plants.

Source: Wikipedia via B Wrigley The heat exchanger is a very important device used in many real world applications in which heat must be transferred from one medium to another. In many cases, the two mediums are separated by a solid wall, although in some cases the two mediums are in direct contact with each other, so that mixing occurs. Standard Solvers. Freesteamplus - Thermodynamics materials properties package for MATLAB. The goal of this project was to create a library of MATLAB functions for calculating the thermodynamic properties of various materials.

The software has functions for obtaining pressure, temperature, specific volume, entropy, enthalpy, and, for some materials, constant pressure specific heat. The library includes correlation for steam, R-134a refrigerant, air, carbon dioxide, hydrogen, helium, nitrogen, oxygen, and propane. Inputs can be converted from a large variety of units and all outputs are given in SI units. FreeSteam+ requires MATLAB 2008 or later to run. A Textbook of Engineering Mechanics - R.K. Bansal.
