I am assuming your design comes under ASME B 31.3 (Process piping in refinery), since there are certain allowances like corrosion allowance, usually pipes will sustain hydro load when they are designed for design pressure at design temp. Use formula provided in 304.1.2 and Table A-1 Code also...

I think most of the springs used in Automotive applications (not suspensions) are mass produced, right?

Hey please tell me what is the basic geometry of spar? is it H section? what are the materials used? stainless steel? how to manufacture it? what are the design consideration to be made? can we apply principles of cantilever beam?

Hey guys, how do we define springs? in gauges? or just based on diameter? are there any guidelines in adopting springs in design? any standards available for springs in United states or In India??

LittleInch Can you please give me a link containing standard nozzle sizes of SS available in US? I'm unable to find one

How to calculate the max pressure Nozzle 1/2 SCH Stainless steel can hold? please help

My friend said we could use Nozzle 1/2 SCH Stainless steel... is that not casted part?

If I have to use casted part for Nozzle in LNG tanks (cryogenics) what material I should chose.. thats my question

Hello TVP, Thank you very much.. I'll look into those documents

Hi please enlighten me on the Iron alloys which have Austenitic structure at low temperatures and which can be produced in metal casting

Frank1344, I'm trying that option too, Thank you :) btrueblood, Sorry buddy I am not aware of Stainless steel machining, I think it is hell of a cost anyways Thank you

Thank you guys for the responses I was searching in matweb about the material J434.. I got the results for UNS F33100 Cast Iron/ 65-45-12/ SAE J434 D4512 among the above three which is Standard nomenclature?

among cast irons which type of cast iron is strongest? is there any moneclature...for eg in steels we have ss 304, ss 317

Hey guys, as per my understanding we cannot cast Stainless steel and machine it, correct? So I am thinking of cast iron to use for part which has to bear some shear load... Can someone tell me Cast Iron types which have higher Yield strength? and another question between SS 302 and SS 329...

BingINch, thank you very much, I'll try to understand how it arrived.. :)

How viscosity of Air is effected in reduced pressures? The polynomial function viscosity will give viscosity at any temperature, http://hpce.iitm.ac.in/website/Manuals/Fluent_6.3/fluent6.3/help/html/ug/node337.htm But how to find viscosity of air when both temp and pressure are changed? The...

Ione, I understand convection is small in this situation, I'm trying to find out how small

EnergyMix Sorry for late response, firstly it is not a school assignment, I like heat transfer so I'm trying to learn and understand the subject more I'm trying to understand the heat coming out from a Thermos flask, after the partial evacuation of gap in between flasks it might come around...

i was asking for a function which will help me to find viscosity at given pressure and temperature

There's a polynomial equation for Kinematic viscosity at different temperatures But what if I we pressure and temperature both are changed, for example in partial vacuum Is it possible to find viscosity of air at 3pa pressure and 200K temperature? How to find convective heat transfer...
