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.

What sort of heat duty is required for your application in mind? Have you thought about doing any numerical modelling based on your design?

If you have Matlab you can download a simulation package called ADVISOR for free and simulate your fuel consumption at different ambient temperatures.

Finding heat transfer coefficients is very difficult, usually such data is gathered experimentally and then estimates can be made based on that.

Although if anyone does know how they would solve it via something like my original route, it would still be useful.

obafgkmrns, thanks. I've solved the question using your recommended approach , and I've attached the working just for closure.

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...

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...

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...

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...

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...

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...

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.

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!

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.
