A saturated steam table is an indispensable tool for any engineer working with steam. It's typically used to determine saturated steam temperature from steam pressure, or the opposite: pressure from saturated steam temperature.

In addition to pressure and temperature, these tables usually include other related values such as specific enthalpy (h) and specific volume (v).

The data found in a saturated steam table always refers to steam at a particular saturation point, also known as the boiling point.

Saturation point is the point where water (liquid) and steam (gas) can coexist at the same temperature and pressure.

Because H2O can be either liquid or gas at its saturation point, two sets of data are required: data for saturated water (liquid), which is typically marked with an "f" in subscript, and data for saturated steam (gas), which is typically marked using a "g" in subscript.

Notations used are:

  • P = Pressure of the steam/water
  • T = Saturation point of steam/water (boiling point)
  • vf = Specific volume of saturated water (liquid).
  • vg = Specific volume of saturated steam (gas).
  • hf = Specific enthalpy of saturated water (energy required to heat water from 0°C (32°F) to the boiling point)
  • hfg = Latent heat of evaporation (energy required to transform saturated water into dry saturated steam)
  • hg = Specific enthalpy of saturated steam (total energy required to generate steam from water at 0°C (32°F)).

Though each company has its own drafting standards, the practises set forth in this post may not be exactly the same practises followed in all corporations.
The practises given are in general agreement with recommendations set forth in ANSI standards.

  1. Place dimensions outside the view. Unless they will be more easily and quickly understood.

Dims_outside

2.Place dimensions between views unless the rules such as the contour rule, the rule against crowding and so forth, prevent their being so placed

3. If possible avoid crossing two dimension lines

Crossing_dim_line

4. A centre line may be extended to serve as an extension line

Center_line_extension

5. Keep parallel dimension equally spaced

parallel_dim_eually_spaced

6. Always give locating dimensions to the centres of circles that represent holes, cylindrical projections or bosses.

locating dimensions to the centres of circles

7. If possible attach the location dimension for holes to the view on which they appear as circles.

Attach the location dimension for holes to the view on which they appear as circles

8. Group related dimensions on the view showing the contour of a feature

Group related dimensions on the view showing the contour of a feature

9. Arrange a series of dimensions in a continuous line.

Series of dimensions in a continuous line

10. Dimension from a finished surface, centreline or baseline that can be readily established

Dimension from a finished surface

11. Stagger the figures in a series of parallel dimension lines to allow sufficient space for the figures and to prevent confusion

Refer above Figure

12. Do not repeat dimensions

13. When an arc is used as a dimension line for an angular measurement use the vertex of the angle as the centre. It is usually undesirable to terminate the dimension line for an angle at lines that represent surfaces.it is better practise to use an extension line.

Angle_dimensioning

14. Place the figures of angular dimensions so they will read from the bottom of a drawing except in the case of large angles.

Whenever, I get chance to meet and interview any mechanical designer, I could see they will be more interested to showcase themselves knowing more about a different mechanical CAD software it could be Catia, Solidworks, Pro-E etc.

Resume will be filled with all the CAD software name but as soon as you ask them why did they use the particular software to design or if you have ask them about product function,manufacturing process or about tolerance & fit, people will start blinking their eyes,because every mechanical designer think designing is all about extrude,revolve ,sweep or blend option which is available on any CAD platform today.

But I have simple question how long can you survive with this CAD knowledge ?Answer may be 5,10 or 15 years but what is next ?

So to be good designer,you need to be follow or must adapt below thing with your CAD software knowledge

1. Understand the function of the product on which you are working

Before you start designing on any CAD platform, always ask below question

  1. What is the project all about?

  2. Why are we designing this product?

  3. What is function of the product ?

  4. Who is end user ?

  5. What is customer expectation from us on this product?

  6. Are we designing for the right functionality?

Because knowing the functionality is very important,ultimately customer is going to pay for the function, if you have product that look good and have nice aesthetic but did not serve the function for customer,product will fail in the market.

2. Manufacturing Process

Every Designer should and must be aware of the basic manufacturing process such as Casting,Injection molding,Machining & Stamping process, because most of the mechanical industries use it to produce your product from virtual CAD to real product which customer will use it as end user.

To be real product designer,he or she must be aware or have fair understanding how his product can be manufactured once it is out of the CAD platform,it will help him to make better design than others, by adding better features without increasing the cost of the product.

According to me, without knowing manufacturing process,"It is like heart without soul" for the mechanical design engineer. :)

3. Material Selection

It is very much important to have fair knowledge on the material selection,product which you will be designing on the CAD platform has to come to real world to the consumer,so it is very much important to know about what material you are going to select for the product.

We have seen lot of real life example of effect of the wrong material selection,product is either recalled from the company or failed in the market due to it.

Ultimately, Mechanical is all about reality, we cannot work on the virtual CAD world, Mechanical product will be feel by the customer in his hand.

4. Market or Competitor Awareness

This is one of the important parameter in today's world, as design engineer you should be aware of your competitor and their product & technology,you should always think beyond of your competitor to be succeed in the market. Always have greater vision.

Darwin theory - "Survival of the fittest" in the today market.

5. DFX

X-factor is very much important in the design process, when somebody design product it should have all the X-factor included in his design such as ease of manufacturing,assembly & mistake proofing (POKA-YOKE) etc.

6. Tolerance & Fits

Product design is all about the 3 F's Form, fit and function,if your product need to be function properly,you should choose right tolerance and fit ,it does not mean by tightening tolerance your product will function properly,it is one of the wrong perception of the people,please avoid it

Select right tolerance & fits because

Cost & Function is directly proportional to tolerance & fit. :)

Hi Phani, I am a design consultant & cad trainer.I am working with Autocad, Solidworks, NX, Solidedge softwares.There are other softwares as well in demand like Pro-Engineer, Catia etc.Once you are expert on using any 3d software, you can handle almost any of them as per requirements.Autocad is basically a 2d drawings software (for mechanical engineer's usage ) & is required to be along with 3d softwares.So I would suggest Solidworks, NX, Pro-E with Autocad.If you get enough exposer to any 3d software with ability to design/3d models/drawing of parts/products/machines,you can get good chances of better employment in any industry.But as we know learning is an endless process along with job,we should keep grasping new things everyday. read less
