Thanks, BK. At my previous employ, we had a number of large Ingersoll mills but I was not aware that they had any experience with large lathes. I will certainly contact them. Goosen

Related to the question listed below. I am looking for a list of current manufacturers of long lathes. I need a Center-to-Center length of 60-75 ft. with a 3-4 ft swing. Are there any manufacturers of large lathes left in the US? Thus far, I have identified Skoda (Czech Republic) and Poreba...

I am with jetmaker. Design the hitch attachment such that the bolts *will* carry the load. Unless you have performed testing on similar components with a similar surface finish, etc, I doubt that you know enough about the coefficient of friction to depend on it for your design to succeed in...

I accidentally poured 1/2 quart of straight 30W with 6 quarts of 10W30 while changing the oil in my '91 Previa. Will this damage the engine? (Castrol GTX) Goosen

vanstoja, A colleague did a simple CFD analysis and your result comports well with what he found. It is somewhat "bad news" in that we were hoping the leakage would be much less than this, but "the facts is the facts", as they say, and THAT is why I like practicing...

The gap length is 0.060 in. Thanks again for your efforts, vanstoja, I really appreciate the help. Goosen

Oops, I left out some text in my response. It should have said, **************** Hacksaw, I tried the approach that you recommend early on and I have difficulty accepting the results. That is, the flow seems higher than I would expect. That is not to say that it is not approximately correct...

Vanstoja, Thank you for the references. I will investigate them. I also appreciate your time spent iterating with the spreadsheet. Please let me know if you can confirm the sample problem results. Hacksaw, I tried the approach that you recommend early on and I have difficulty accepting the...

Thanks for confirming my understanding of the problem, Bob. I only have my undergraduate Fluids text and it does not address this problem. That is why I am here seeking the expertise of this gathered assembly. :-) Goosen

Thanks for the link but this refers to an orifice in a pipe. My problem is a bit different since it involves an annulus. My understanding is that simply determining the area of the annulus and converting that area to an orifice diameter is not an appropriate approach. Goosen

Greetings Mechanikals, I need some help in determining the flow through what I will call an “annular orifice”. 1. I have a smooth pipe with an inside diameter of 24 in. 2. Centered in that pipe is a thin plate with an outside diameter that is 0.08 in. smaller than the inside diameter of the...
