I'm trying to find a copy of the HPTA High Pressure Safety Code, put out by the High Pressure Technology Association in the UK in the 70's. Any hints or clues? I have a nice description of it in the 1975 High Pressure Engineering conference proceedings from IME, but am running into a brick wall...
I need a lab to do air filter media performance testing per ISO 5011. Any suggestions? (I can't use SWRI because of a conflict of interest on this project).
Thankx.
Info from Allison on truck transmissions says to not tow w/o disconnecting driveshaft.
What's the problem w/ towing w/ driveshaft? Could I do it if I leave the engine running to drive lube pump? (I'm specifically thinking of a cement truck where you would want to leave the engine running to...
Is anyone familiar with a pressure-relieving flange gasket?? It reportedly fits between 2 pipe flanges like a regular gasket, but blows out when a given pressure is reached.
If I have a brew of hydrocarbons (eg. mixture w/ aliphatic diesters)
that has a published VOC of 7.813 lb/gal,
is there any way to guess a molecular weight of the vapor??
(vapor pressure = .200mmHg @ 68F)
If I have a solution of one liquid, say gasoline, of known vapor pressure,
dissolved in another liquid of known vapor pressure, say diesel fuel
- what's the vapor pressure of the solution?
Hi.
I'm trying to calculate the concentration of vapor in a tank containing liquid #2 diesel fuel & air. I have numbers for vapor pressure, which would let me calculate the concentration if it were an ideal gas or other pure substance. Is there a rough approximation of an equivalent molecular...
I'm doing some estimates of choked flow of methane thru a leak in a pipe. Any recommendations for what coefficient of discharge to use? I have used 0.6, but I've seen some examples on the web of 0.72.
My current problem is a 1" hole in a 1-1/4" elbow (1.38" ID),
but I'm also...
I need to do some simple estimates of gas leaks from a pipe. Is there any shareware that does compressible orifice calculations? I don't need anything fancy, just some basic equations.
Thanks.
I'm preparing a talk on mechanical failures that can cause auto accidents. Does anyone know of any websites, books, or articles that would have any statistics, photos, or interesting anecdotes??
Thanks,

I'm considering PHOENICS and PORFLOW CFD packages to model flow of gases and liquids through porous media, such as soils. They both seem good - PORFLOW is more specific to my current need, and PHOENICS las lots of additional capabilities that I might be able to use on other projects. Any...
I'm looking for a FEA package that can model laminar flow through porous media - primarilarly gas, but possibly also liquid flow. At the moment, I'm thinking that I might be able to use a low end application to run simple models, although I'm certainly aware that these assumptions can rapidly...

I'm attempting to make a rough estimate of stresses due to mechanical bending of a sch 40 PVC tee. What are some good sources for a stress concentration factor?
I assume that what's generally available are stress concentration factors for hoop stresses from internal pressure. How about for...
