If doing a thermal analysis of a 19" x 6 foot high enclosure, with a computer mounted in it, would you select "external" analysis if you wanted to see how hot the inside of the computer was getting? There would be an exhaust fan mounted at the top of the 6 foot high enclosure. The computer...
In Creo 4.0 if you know that you want your finished model to be parametric and to have holes located as basic dimensions coming from particular datums, do you have to create the model as such initially, or can you just locate the holes in the model using the linear dimensions coming from the...
In CREO 4.0 if you are creating a model and you locate a hole from one edge of a part and then later use the Geometric Dimensioning tool and locate the same hole with a basic dimension from a different edge of the part, which dimension will appear on the drawing if you use the "Use Model...
I am dimensioning a part that has holes put in on the front side and the back side. I am using basic dimensions for the hole locations and true positional tolerancing. Once I show Datums B and C for the surfaces of the part in the front view, is it OK to show them again in the rear view of...
I have 3 alum plates bolted together using two bolts several inches apart. I have clearance holes in each of the two top plates. They are then placed down on top of the third plate, which has two tapped holes for the bolts. Is this a valid equation for determining the size of the smallest...
1. If a chiller is designed to provide 3 gpm at 80 psi and we have a pressure drop of 20 psi in the equipment cabinet we are cooling, would you still have 3 gpm flow through the copper tubing in the equipment cabinet?
2. When our equipment is turned on and heat is being generated and...
I need to do a thermal analysis to make sure that the electronic equipment items in a 6 foot tall metal cabinet are not getting too hot when they are all running. The cabinet has solid walls on two sides, a door on the rear and a top. There is no front door. The equipment is placed into the...
