what about bolt circle diameter

Can someone tell me how to calulate the size and number of bolts I need to secure a cylinder that is holding internal pressure. Simply a cylinder with an OD and ID and one end is open that needs to have a plate screwed on to the top to hold the pressure. This should be very easy calculation.

Here is where it gets interesting: The can is going to hold a certain type of tobacco. The purpose of the can is to do the following: Hold the tobacoo and when the consumer gets the product he/she can peel off (that is what we have talked about) a tab or something and then underneath the tab...

Is it possible to get a Prototype made of a can. If not what do you recommend? How thick of sheet metal is a can made from? Since this is not holding a pressure but still must be two piece do you recomend using the same material for both ends? Would you seal in the same manner as a coke can is...

My MBA friend is starting a company where he needs the following done: A small can (about 1/5 the size of a coke can) that will be a two piece assembly (just like a coke can). This can will hold a certain type of product which does not need internal pressure but this can must be sealed...

Use a Teflon energized seal. We use these for cryogenic applications for LNG which is down to -260 F and they will not leak. We test these with the same applications that you do but it is a flange to flange connection and we have gotten as high as 3000 PSI and been succesful. Information on...

I am familiar with everything you said. I want to keep it very easy for the prototype and then make it very precise after. Can you give me any hints on where to start

I am a mechanical engineer and want to design an automated Bartender. This is just for fun. I need to know how I can control fluid in a pipe. The pipe will be set up verically and be blocked off by a valve or something. Then I need to do a control of somesort to tell the valve to move at a rate...

In the industry that I work in they have always used shrouded impellers and I am now wondering why. Looking at the alternative and not using a shroud I see a a possibility of easy maching (CNC with great surface finishes), no efficiency loss from wear ring clearance, and less material so lower...

Thank you very much. Now I just need to figure out if it will be a smart decision to through a VFD in to save money. Seems that a VFD will be more expensive along with the fact that bearings must now changed and serviced more.

I would like to know if there is anyone out there with experience in high pressure cryogenic pumps (LNP,LPG etc.) I work in this field and am looking for people to discuss technical issues. Thanks Cryopumps

I am a cryogenic pump engineer. I recentley designed a pump in the 1250 specific speed pump at 3560 RPM (7960 FT at 1570 GPM, liquid is LNG). The diameter of the impeller that we used came out to about 13 inches and it was a 14 stage pump. My question is would it be usefull to speed up the motor...
