Hello,
I explained in another thread my current business-hobby about various thermodynamic cycles.
(see http://www.eng-tips.com/viewthread.cfm?qid=262808&page=1)
I would like to find a nice T-s diagram for pentane.
In many papers such diagrams are given schematically.
However, I would like to...
Hello,
I have been asked an advice about waste heat to power systems (say wh2p).
The available waste heat to be considered is a (dirty) gas in a temperature range between 250°C and 450°C.
The useful power that could be generated would range between 2MW and 10MW.
I know some examples based on...

Hello,
For the holidays period, I would like to have some fun with the Excel drawing features.
I am using the Excel drawing features quite a lot for representing flowsheets.
Besides, I have also developped a specialised class library that I am using in Excel to calculate the flowsheets.
So the...
Hello,
Here is a simple flowsheet:
|input>|pipe1>|fan1>|filter1>|neutral point|filter2>|fan2>|pipe3>|output>
In this flowsheet:
- the fluid is air
- the input and output are atmospheric pressure
- there are two fans
- there is a "neutral point", whose pressure should be close to...
Hello,
I have to analyse the sizing and control of a small pipe and fans and filters network. I find no fun in doing that the way I did it some years ago.
Would there be some (possibily free or cheap) software available for this?
The needs are rather modest.
The network of pipes is a tree...
Hello,
I would like to find the best available formula for the acid dew point.
Composition of the flue gases would include: O2, N2, CO2, SO2, HCl .
Thanks
Hello, I am going back to the basics with my question:
- let us assume we have flue gas at 250°,
- let us assume its composition is nearly that of air,
- let us assume the cold source is at 25°C,
- let us finally assume this stream carries an enthalpy-power of 10 MW (calculated from 250°C to...
I developed a useful excel add-in:
- it helps maintain custom document properties
- it can search files (xl, doc, ...) on this basis
- I used a local "Indexing service" catalog
It is written in VBA, and uses the FileSearch object.
Collegues would like to use it on a network...
Access reports are very attractive but they cannot be exported in a convenient way. Therefore the only way to distribute an Access report is paper, as far as I could see.
I tried exporting them to Excel and I got an awful result.
I tried exporting to Word without more satisfaction.
Using...
I would like to find a concrete mix database, possibly on the www. My purpose is performing correlations between the following:
- recipe (cements,water,agregates,additives,...)
- properties (slump,stengths,setting time,...)
I could already find a paper with about 30 recipes...
I extensively use MSOffice document properties for indexing projects documents (xls,doc,ppt)). ('custom'document properties are encoded with a home-developed screen in word/excel or ppt)
I would like to extend this procedure to .pdf and .dwg files.
Any suggestion on how to proceed?
Does someone know of a (free) Principal Component Analysis tool for excel.
Ideally, I would prefer VBA source code (or even short fortran).
I could partly do the job by calculating the correlation matrix (CORREL excel function) and diagonalisation.
