There is a wrong example: risk category III Our mechanical engineer use V1700, divided by 0.78, (they think that V1700/0.78=V50, and they think VT/0.78=V50) Then they use "V50" and consider importance factor 1.15 for risk category III. I am not that familiar with the ASCE 7 code and all the...

I just saw your new post after I posted my last response. I will look at it tomorrow, it is getting late here.

There must be some wind speed maps somewhere. There must be building codes for your area that specifies wind speed for structural engineers to design buildings. I would ask a structural engineer for wind speed maps for 50 year MRI wind, 3-sec gust, Exposure C, and use those values without...

I see that there is some confusion now in API 650 conversion requirements. Do you convert to V50 MRI using ASCE 7-10 equation then multiply by 0.6/0.78? or do you take the values straight from the V300, 700 or 1400 wind maps and multiply by 0.6/0.78. There are three possibilities per API 650...

If now strength wind speed V1700 is provided, how should we calculate wind load as per API 650? I think that only formula provided in Page 509, ASCE 7-10, is effective. V1700/V50=[0.36+0.1ln(12*1700)] So as per Chapter 5.2, API 650, load combinations, we can use V50, considering importance...

Yes but a the importance factor, and other factors, is applied after the theoretical wind pressure 0.00256V2/2g is calculated. Here is a typical older calculation based on before ASCE 7-10 for a pressure vessel (same for piping). I remember now that somewhere along the way ASCE started...

Part 4 of 4 For the ASCE 7-05 conversion indicated in API 650 (2013) above in paragraph k) first sentence, since the load factors and importance factors are not included to begin with in ASCE 7-05 wind maps, then the ASCE 7-05 maps are the true 50 MRI, 3-sec gust, 33 feet level, Exposure C...

Part 3 API 650-2013 API 650 – 2013 added complete new requirements for determining wind load in Section 5.2.1 (k) for the purpose of being consistent and adjusting for the revised wind maps of ASCE 7-10 which included the importance factor and LFRD load factor directly in the wind maps. The...

Part 2 API 650- 2000 API 650 (2000) requirements for overturning resistance as below in Bold. Note this is the only reference to wind loading in API 650 (2000). There is no indication of wind loading requirements for design loads in “Design Considerations” section, as it is left up to the...

Part 1 Wind load equations per ASCE 7-05 or earlier takes the Basic Wind Speed and calculates the wind pressure based on this speed. The Basic Wind Speed per ASCE 7-05 and earlier editions is based on 3-sec. gust at 33 feet elevation, Exposure C, and 50 year MRI. However, note that ASCE 7-88...

Mechanical wind load calculations are performed in accordance with the national, state, local regulations, and specific to industry. Typically, the most common Standard used for mechanical wind load calculations is ASCE 7 methods but for oil and gas offshore platforms the requirements of API RP...

Seismic along with wind loads are considered Occasional Loads by ASME B31.3. A stress analysis for piping includes these loads along with thermal loads, internal pressure loads, etc. There are no separate calculations for seismic loads by other 3rd party design firms. The design engineering...

In your first two equations you have set up as if areas A1 and A2 were constant. They are constant on the left side of the equation but not constant on the right side but "A" is a function of "x". Total area to calculate weight is not therefore A1(x) or A2(x) on the right side but the summation...

See attached Olet catalogue page 25. It is an old catalogue but you can get the latest from the manufacturer website.https://files.engineering.com/getfile.aspx?folder=28675070-7878-4f65-85f4-71eec716d1e6&file=OletCat.pdf

Elbolets are used on elbows.

Also condensation will occur only if the air is saturated with water vapor. If the steam disperses well into the air and the air remains above dew point then no steam will condense.

this is a 160in long catch that is loaded evenly with load up to 2000lb (I'm trying to get this down). What physically does this actually look like? And what do you mean by I want the deflection at that point so that it can slip its catch and not be restrained at point B anymore. releasing...

Check out this good video on simple beam theory.https://files.engineering.com/getfile.aspx?folder=3f90e05d-4140-4437-ba35-7948283e0e1a&file=Simple_Beam_Theory_Video.mp4

Once the steam enters the atmosphere it is at 14.7 psia and will condense at 212 F. It is initially superheated and loses heat then reaches 212 F and condenses this may or may not be at 1 meter from leak.

I don't have any preventative maintenance data or manuals from that project. However I did a search on the internet for: installation operation manual HPcp barrel casing pump type BB5 There is a lot of links and references that come up. I have even found the Goulds Installation, Operation...
