Hello all,
I hope this is the right forum for this question. I work at a valve manufacturer and we assemble and perform hydrostatic testing on nearly all of the valves. Due to recent safety incidents, the company is trying to put together a "standard" for test bunker design. We are currently...
Anyone familiar with API 11S2 spec? More specifically interpretation of the 5% tolerance band on the rate curve and how to determine % diff of an actual measured point from catalog curve? I have attached the spec. for reference.
Hello all,
I have a question concerning the best method/approach to testing the integrity of both our low voltage (480v) and medium voltage (cables). I have read that DC hi-pot testing is destructive for aged cables, which is what we have. I have also read the PD testing is a good alternative...
Hello all, I am new to this forum so bear with me :)
I am looking for medium voltage (we use primarily 4160v and 6300v)quick disconnect plugs and receptacles. We use a lot of 480v and are easy to find for low voltage, but I have yet to come across any for medium voltage. Do they exist and if...
Makes total sense now, since someone has explained it to me. Different subject here but do you have any recommendations on a good FEM book, can be either Solidworks simulation specific or not.
thanks.
I assigned plain carbon steel from Solidworks materials. When I apply a fixed constraint on the two cylindrical surfaces it yields much more acceptable results with a max. displacement of .00013". I assumed that fixing the bearing surfaces instead of constraining radial, translational defeated...
Hello,
I am performing a static study in SW '10 to determine the max. radial displacement of a rotating piston rigidly attached to a shaft rotating at 3600 RPM. I actually have the piston and shaft drawn as one part and have two bearing journal surfaces on the shaft where I am applying fixtures...
I found a program that calculates dP in an annular orifice, it's called Pipedrop from G&E Engineering. The results are very close to the formula listed above in the link I sent. I think the best approach is to build a simplified test apparatus and gather real data. Thanks for all the posts guys.
Wow, that result is much different than I anticipated using the link below from a fluid power handbook. I calculated the effective area using the Petroleum engineering on your post and came out with a lot lower pressure drop than the formula used on the link below. Copy and paste it into your...
Anyone have a formula for pressure drop through an annular ring. I have found very limited information on the web, but from what I've found the pressure drop is different than that of an orifice because there are two separate surfaces with the ring. Any advice would greatly be appreciated.
My bad, I guess I posted this in the smarta*s forum by mistake :). I am fully aware there is no substiture for paying a PE to give professional advice, however I thought I would try to get some preliminary advice from people who might have some experience with a similar structure. Anyway...
From the limited resources I've found online on ACI 350R (thanks delagina), it lists 8" for a minimum thickness for walls under 10'. It also lists a maximum spacing of 12" for rebar, sorry for the dumb question, but would this be referring to the vertical supports only or both vertical and...
Boy I hope you're right delagina. Right now we're thinking 8" but that's based on the "good ol' boy" philosophy of bigger is better or someone could say the "industrial engineer" philosophy :)
That was a great game, huh a2mfk?
Hello,
I am building a water containment wall surrounding process water tanks. The wall is boxed in to form a rectangle, dimensions are approximately 500" W x 300" L x 55" H. So the maximum pressure the wall would see is 55" of standing water. The wall will have rebar going into existing...
