I am trying to find the exit velocity of the steam coming out of a steam condenser turbine. The inlet pressure is 1312.46 psia with a temperature of 867.67 F. The exit pressure is 7.84 psia with a temperature of 182.97 F. The mass flow rate through the turbine is 220,000 lbm/hr. Am I right in...

I am currently working on a project involving hardware ranging between 1/4" and 5/16" diameter. One of the requirements is that these items must have a minimum energy absorption of 20J @ -20C per ASTM A370 (10 mm X 10 mm sample). From what I can find the smallest sample size specified in ASTM...

I have attached a model I am working on in NX6. I am trying to create a smooth transition between the two faces. I have tried a multitude of things but am not seeming to get it. Any help with this would be greatly appreciated. Thanks in advance, lurks

For some reason, whenever I go to add an annotation, ID symbol, etc. the lettering angle defaults to 90.99 degrees. How do I get it to default back to 0. Thanks in advance, lurks

I am trying to create what I think is a lofted flange. I am trying to go from a 3/8" full radius to 1" wide flat. Can this be done in sheet metal or do I have to do in modeling? Thanks in advance, lurks

When I go from modeling to drafting some of the lines that are part of my model do not show up. For example if I am trying to make a drawing of a bolt assembly the line representing the edge of the bolt disappears from the bottom of the nut to the end that is chamfered. Does this make sense...

I have been researching performance modifications for a 4 cylinder turbo car and had a question about tuning. When you purchase a "canned" tune to flash to your ecu what parameters are changed? My understanding of a vehicle's ecu is that it is a closed loop system that will automatically...

I am trying to add a component to an assembly and am getting the following error: "All objects in the previewed part are on invisible layers for the currently selected reference set and layer options. Consider changing the reference set or layer settings." This particular component was created...

I am working on a drawing where a section view is necessary. I have no problem creating the view but I would like to know how to adjust the overall width of the cut line. It is currently 4 - 5 times wider than the section that I am cutting. Does anybody know how to do this? Thanks in...

Hi all, I am trying to model a helix that is formed out of 3/8" thick sheet steel on a press type form die. I would like to model this within NXSheetmetal and be able to see the flat pattern. Is this possible? Any help would be greatly appreciated. Thanks in advance, Lurks

I am trying to obtain a section view from a broken view. It is telling me that I have chosen an invalid view. Am I trying to do something that is not able to be done? Thanks in advance, Lurks

I am trying to duplicate the flared lip shown in the attached drawing. I am not sure as to how to go about this due to the fact that it is not constant around the entire radius. The angle goes from 15 degrees to 0 as it approaches the tangential point that the straight side meets the radius...

I created a plate in NX Sheet Metal that has two holes punched in it. The plate is then curved as if around a cylinder. After doing this I tried to dimension in drafting. With this I was unable to select the holes in order to add a diameter dimension. Is this not possible using the modeling...

Does anyone know of any good reference material related to the compressible fluid flow through the internal combustion engine? I have yet to find what I'm looking for. Thanks, Lurks

I have modeled a bolt on which I applied text to the head to signify the necessary head marking. I then took this part and put it into an assembly of the bolt and nut combination. When I did this the text that I had applied to the head disappeared. Does anybody know what I need to do in order...

When inserting a weld symbol in drafting mode I am not able to find how to include the symbol that would imply that the weld is all the way around. This would be a circle at the point of intersection on the leader. Thanks in advance, Lurks

I am trying to apply a knurling to a round bar, and am having trouble coming up with the best way to do this. Has anybody done this before or know what the best way to do this would be? Thanks in advance, Lurks

I have a long piece that I am needing to apply a broken view in order to fit the desired format. The problem that I am having is applying the same broken view to both the front and top view. Is there an easy way to do this? Any help would be greatly appreciated. Thanks in advance, lurks

I am trying to design a part that requires an interference fit of an extruded HDPE pipe .79" OD and .55" ID into a base of the same material. What is the rule of thumb for diameters and tolerances for an interference of plastic into plastic. I have formulas that would work for metals, but do...
