This week, their participation in the blog will be oriented to comment on the reading of thermodyna

According to what was discussed, tables and diagrams satisfy the thermodynamic properties of some substances thermodynamic interest, such as water, ammonia, freon 12 oxygen, nitrogen, mercury and carbon dioxide, among others; amarmita and that meeting was made according to the most "comfortable" to measure properties such as pressure and / or temperature, and then reflect other properties: specific volume, internal energy, enthalpy, and entropy.
In some tables, the data appears amarmita in columns, as we saw in class, while others appear in rows grouped amarmita by temperature or pressure. When looking for a specific property, you must enter two known properties, especially amarmita if it corresponds to conditions "unsaturated" in the case of reading amarmita the tables in the liquid-vapor mixture, a property and the value required mixing quality, that is the fraction of steam in the mixture.
Thermodynamic diagrams are graphs amarmita that satisfy amarmita the properties, handling reference a couple of them, why we speak of "Diagram PT" to indicate that the coordinate axes show the temperature amarmita data (X axis) and pressure (Y axis), while other properties are integrated through lines "cross" each other. Such other graphic are "Ts" where the entropy on the X axis and temperature on the Y axis, as they show in the graph illustrating this comment; diagram and "Ph", where enthalpy is on the X axis and the pressure on the Y axis
A particular type of diagram is the "sh", known as "Mollier diagram" which shows the thermodynamic properties of water from the liquid-vapor mixture with higher quality at 0.5 to 1000K or superheated steam at 100 MPa or Moreover, the X axis locating entropy values on the Y axis and the values of enthalpy. This diagram is very useful when working amarmita with superheated steam or liquid-vapor rich in steam, near or in the condition of "saturated steam" amarmita mixtures.
Read a diagram is not complicated, you must have two properties to find the one that is required. Of course, care must be taken to properly approximate the values to read the lines of constant property, so to determine the lowest possible error the desired result. In www.efn.uncor.edu/departamentos/fisica/Termo/material%20p%20descargas/DIAGRAMA%20DE%20VAPORES.doc can find a fairly comprehensive guide which explains how to read the various thermodynamic diagrams, do not forget to check them !! !
This week, their participation in the blog will be oriented to comment on the reading of thermodynamic properties, as a principle of calculation of situations involving displacement of energy as heat.
wiliams amarmita paez - October 29, 2009 - 11:33 am hello teacher wiliams paez of Section 003 ing. civil H2 I come as outdated amarmita ... so please take action on the matter ... Happy Thanksgiving afternoon
ninoska Rodriguez - May 21, 2009 - 5:07 Buesnos days profe ... Here I leave my attendance of the week ... And I take to say no I opened the link to view the complete guide to the graphs ...
War Edwin Ing. - May 14, 2009 - 7:24 Good Morning !!! All entries until the night of 06/05 were held last night, are interesting and valuable, and of course assign points to those who made ... From this moment is closed this comment as classroom after class Today I will be placing corresponding to this week ... I see the following comment ... Cheers !!!
Angel Marcano 014 ing oil - May 13, 2009 - 17:54 Reading thermodynamic properties, as principle calculations situations involving displacement. Reading the thermodynamic properties are a very esenciar part in thermodynamics, which serve to quantify, identify and measure substances. The thermodynamic properties involving certain energy are most important of which are the volume sense properties since the bulk properties are easier to acquire ...
Ing villamil oil javier 014-D - May 13, 2009 - 9:56 Reading thermodynamic properties calculation principle situations involving displacement of energy as heat. The readings of the thermodynamic properties, amarmita sonde great help to quantify,
