    PE for American living in Mexico

    He is American, with a BSME from a US accredited school, and passed the FE. The issue is living and working in Mexico City, and seeking to become registered appropriately, without the benefit of working under a US registered PE for the next several years. In the future, he wants to be able...

    heat transfer - wetted perimeter vs. heated perimeter

    There lies the confusion... I can understand the logic behind using the perimeter of the inside pipe, aka, the "heated perimeter". But I have been unable to find any definitive and independent verification of that logic. For example, two references make use of the "hydraulic...

    use of heated perimeter for HX calcs

    In the design/analysis of a double-pipe heat exchanger, is it correct to use the "heated perimeter" for the annular flow, or should the "wetted perimter" be used? For example, I have ethylene-glycol flowing in the annular space, with water flow in the inner pipe. I am...

    PE for American living in Mexico

    Anyone have information on engineering certification and Mexico? My brother passed the FE exam and worked for a year in the states before moving to Mexico. He wants to get licensed (mainly for future use), but not sure if it is possible. And if so, who should he contact and what hoops need to...

    Float Degregation

    This sounds very much like "Critical Chain Project Management" (CCPM). I'm not terribly well-versed in the methods, but there is a very active discussion group at CriticalChain@yahoogroups.com if you want to learn more. There are some very informed people that will most definitely...

    minimum thickness for nozzle necks

    I do not have access to the BPVC itself, but I do have a summary in an engineering text which describes the criteria for required thickness of a nozzle neck as the largest of: (1) the thickness computed from the loadings (internal pressurization, reactions, etc.) plus an allowance for corrosion...

    overview of ASME pressure vessel design code

    Can anyone recommend a free or low-cost source which describes details of the ASME code for pressure vessel design? I would prefer something available on the internet. I don't currently work in this field, but I still consider myself a student, and would like to learn more. Since the actual...
