For wet steam, the values of specific volume vinternal energy uenthalpy hand entropy s are calculated with the following relations. On further heating, the temperature of wet steam remains constant and all the water particles in suspension are converted into steam.

If one knows the psychology behind this team or group development it would become easier to glide through the various stages. This is not of course permissible when x is very small.

## Steam Table And Mollier Diagram

No HTML formatting and links to other web sites are allowed. Extensive properties in superheated vapor state vapor region. First it is necessary to find whether the steam is wet, dry saturated or superheated. The steam table and mollier diagram of superheated steam are given as shown in Table The lower portion contains the values of wet steam, whereas the upper portion contains the values of superheated steam.

The properties in Steam tables have been determined experimentally.

### T&HE: LESSON – 21 USE OF STEAM TABLES AND MOLLIER CHART AND NUMERICAL PROBLEMS

The values of internal energy of superheated steam u sup is calculated by using the following relation. In the following discussion, the Steam tables and Mollier chart are used to demonstrate the use of steam tables and Mollier chart to determine the properties of steam in different states.

Steam table and mollier diagram steam tables for dry saturated steam at 7 bar pressure, we have: What is Steam Turbine and how does it work? On further heating, the temperature of water reaches the boiling point.

Finding unknown,v sup. From steam tables for dry saturated steam at bar, we have: At this stema, the steam is called superheated steam. Be the first to comment The commercially steam table and mollier diagram Mollier diagram is truncated from a point beyond the critical point i. In such truncated diagram property of liquid cannot be read. For wet steam we have equation.

Mollier or Enthalpy-Entropy h-s diagram The Mollier diagram is a is plot of enthalpy h versus entropy steam table and mollier diagram as shown in Fig. Being the most popular educational website in India, we believe in providing quality content to our readers.

The values of internal energy u f of water in saturated liquid state and values of internal energy u g of steam in saturated vapor state are calculated by using following relations.

On further heating, the temperature of dry saturated steam starts increasing and it obeys the laws of perfect gases. This diagram has a series of constant temperature linesconstant pressure linesconstant quality linesand constant volume lines.

By using steam table for superheated steam: The various properties of steam of dry saturated steam and superheated steam vary with the variations of temperature and pressure.

Steam tables for entropy of superheated steam. Constant pressure lines 4. The values of specific volume of superheated steam v supenthalpy of superheated steam h supand entropy of superheated steam s sup are directly noted down from Table Steam tables steam table and mollier diagram enthalpy of superheated steam.

Constant specific volume lines 3. These points are very simple but very important while working in a team. Extensive properties at saturated liquid and saturated vapor state. Steam tables for specific volume of superheated steam. Therefore, it is more convenient to use Table Notify steam table and mollier diagram by email when others post comments to this article. You are currently using guest access Log in. This process continues, till steam table and mollier diagram whole water is converted into wet steam.

When the dry steam is further heated, it behaves more or less like a perfect gas. Due to conversion and rounding off the figures, there is a slight difference in the figures quoted in different books.

But this increase is, generally, neglected for all types of calculations. It is advisable to use Steam-tables or Mollier chart directly for easy and accurate estimation of the properties of steam, such as pressure, temperature, specific volume, enthalpy, entropy etc.

They depend not only on pressure but also on the superheating temperature T sup. Steam tables for saturated water and steam temperature.

### Catalog Record: Steam tables and Mollier diagram | Hathi Trust Digital Library

This is a strictly moderated site. Steam at bar has a specific volume of 0. The diagram is divided into two portions by a somewhat horizontal line termed as saturation curve. For any state, at least two properties should be known to determine the other unknown properties of steam at that state.

Steam table and mollier diagram the actual specific volume of steam 0. Do not include your name, “with regards” etc in the comment. Steam is the vapour form of water and is invisible when pure and dry. Extensive properties in superheated vapor taable vapor region The properties of superheated steam are given as shown in Table
