1. ### MATLAB Implementation of Matlab Controllers onto real systems

Hi All, I am an engineer with limited knowledge of the mechanisms with link hardware to software designs, for example in real time control systems, and wonder if you could help me understand what happens. Can somebody explain to me what the typical process might be; let's say for instance...
2. ### Fuel consumption increases during winter?

True but if the tool has been validated against experimental data and is trusted then it is useful; I don't know if Advisor has been put through a rigourous validation process though.
3. ### Spiral Heat Exchanger Manufacture

What sort of heat duty is required for your application in mind? Have you thought about doing any numerical modelling based on your design?
4. ### Calculating Energy of an inlet gas stream; 2 conflicting methods

Homework Statement I want to calculate the energy of an inlet gas stream (I will add heat later but need to know the rate at which energy is coming into the system [J/s]). The fluid is air and I can decompose it into molar flow rates of the constituent gases. I now need to use lookups to...

6. ### Internship Question - Heat Transfer!

Finding heat transfer coefficients is very difficult, usually such data is gathered experimentally and then estimates can be made based on that.
7. ### Dynamics Problem (Find Angular Velocity)

Although if anyone does know how they would solve it via something like my original route, it would still be useful.
8. ### Dynamics Problem (Find Angular Velocity)

obafgkmrns, thanks. I've solved the question using your recommended approach , and I've attached the working just for closure.
9. ### Dynamics Problem (Find Angular Velocity)

Hope you can offer me some help with this question - I feel close to getting it myself but have spent ages looking at it now. Question and working so far is attached. I think what I need to do to enable me to perform the integral is to get theta as a function of time, or instead somehow...
10. ### Relationship betwen pressure and flow in experiment shown

If I set up an experiment as shwon in the schematic attached, where the effective length of the tubing is 25m (this then goes to a short length of smaller area tubing), and the pressure applied is contant, what kind of relationship should I expect between pressure drop and flow rate? I...
11. ### Steam vs Fuly saturated air: Separation

And, if that is the case, it would also suggest to me that if you aim to increase the pressure of the saturated gas, you can achieve more condensation. But wouldn't increasing the pressure also cause an undesirable temperature rise - which means you would have to find a way of preventing a...
12. ### Steam vs Fuly saturated air: Separation

jambaugh, thanks for your help, I appreciate it. With reference to the exponential P vs T diagram here: http://en.wikipedia.org/wiki/Vapour_pressure_of_water Is it right to say that at points above this line, condensation will occur, whereas superheated steam will result at points below...
13. ### Steam vs Fuly saturated air: Separation

For water separation purposes, what's the difference between steam and fully saturated air? I was looking at a certain product: http://www.nciweb.net/combinat.htm And I'm not sure if such a thing would be suitable for separating the water from a fully saturated air stream at about 60degC...
14. ### Venturi tube obeys ideal gas law?

The ideal gas law staes that pressure is inversely proportional to volume. Makes sense but I am confused by what happens in a venturi tube, where volume seems to decrease at the same time that pressure decreases also. I understand that dynamic pressure increases in the throat but what am I...
15. ### Separation of water from air at high temperature

Can a venturi scrubber be used to separate water particles from a hot air stream? I don't really know how these devices work but I know they can separate particles from gas.
16. ### Separation of water from air at high temperature

I'm just saying that by cooling down the hot saturated gas, more water will condense at a lower temperature. Oh and thanks for the beetle example, although i'm not sure that kind of recent material technology will be available to me in my problem!
17. ### Separation of water from air at high temperature

Hmm..thanks for the reply. If I'm interested in separating that water and re-using it in a loop (where at the outlet it will once again be a fully saturated gas), how do you think I could here use a desiccant/deliquescent material for the purpose of that separation? Hope I make sense.
18. ### Separation of water from air at high temperature

How might one try to separate water from air at high temperature (say, 75degC) - if the gas if fully saturated? I understand that you should try to cool it down first to do so, but other than putting it though a heat exchanger is there any other approach you can take? Thanks
19. ### MATLAB Matlab: picking only integers out of a for loop

Hi, I'm new to this forum and only have a few months experience with matlab but am getting to know it. Hope you can help me. I have a for loop which looks like: for f = a:a:b command end Now, I only want to execute this command for the integer values in this loop. eg. if it was...
