    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...

    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.

    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?

    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...

    Fuel consumption increases during winter?

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

    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.

    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.

    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.

    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...

    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...

    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...

    Steam vs Fuly saturated air: Separation

    jambaugh, thanks for your help, I appreciate it. With reference to the exponential P vs T diagram here: Is it right to say that at points above this line, condensation will occur, whereas superheated steam will result at points below...

    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: 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...

    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...

    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.
