Hello Guys,
hopefully somebody can help me the internet hasn't been too helpful. I am doing a material takedown for rebar in a large bridge construction project. Never having been subjected to civil drawings before the progress is slow and painful.
I was wondering if anybody could direct me to a...
Hello guys,
I am looking for a good website on the internet that has thermodynamic properties on Nitrogen (entropy, enthalpy, specific volume...). Thank you very much for any help.

I have a simple optimization problem, but have almost no experience with Matlab. Is there a good tutorial website you guys can suggest to me?
Thank you

Hello everybody,
I am designing a heat exchanger which involves corrosive materials, which excludes any metal as possibilities as materials. I seem to have narrowed it down to PE by comparing polymers with their respective thermal conductivities.
Now I am faced with the choice between High...
Hello,
I am looking for material properties of Tygon, especially thermal conductivity. Has anybody a place they can point me to, the internet doesn't seem to offer too much. Or else can anybody tell me if it is suitable for usage in a heat exchanger.
Thank You

Hello,
not sure if this is the right forum to post the question in, but I have a couple Sensors which I would like to pressure test up to 15000psi in water. Is there anybody that knows of a facility preferably in Canada.
Thanks a lot

Hey guys,
I am currently making a calibration tank for underwater sensors. I am using a heat exchanger to bring the tank to a certain temperature, once it has reached it the heat exchanger will turn itself off and only the stirrer will run during the calibration. I am trying to calculate the...
I am looking for a crude way to obtain the volumetric flow of through a propeller immersed in water. My variables are Pitch diameter RPM density and chord of the propeller. Do I need a coefficient, or an I use the relation mass flow = density x Propeller Velocity x Area. And if I can use it, how...
Just setting up a new heat exchanger system, in it I need a propeller that is able to overturn the volume of the tank in a given time. Could you please point me to the formula that relates propeller pitch to volume flow rate for one revolution.
Thanks a lot for the help

Hello everybody,
I am looking for a nylon spacer for a 2-56 machine screw with a length of 9/32" or 7mm. I have been looking all over but all I can find is a version on McMaster which is over a dollar per spacer, I could get them machined locally for probably less. So if anybody has an idea...
Everytime I change settings in my options, they aren't saved for my next new documents. For example if I want to change the accuracy of my dimensioning, or add automatic center lines, they would be changed back to the default when I open the next empty document. Anybody out there knows what the...
Hi Guys,
I have been looking for the past two hours, but my office computer thinks it is neccessary to display dimension names (D1,D2,D3 ....) in the drawing This has no use what so ever. Could you please tell me where I can turn them off.
Thanks a lot
