Hi all!
I'm trying to get my head around something... on a pressure vessel with an ideal gas when there is a 'leak', or any output of the stored gas, if there is no inlet, the pressure inside the tank decreases (PV=nRT), right?
But with a pressure vessel filled with water, that is...

Hello all!
I have the same question as the thread referenced.
The situation is, ASME B16.20 defines the maximum hardness for 316 rig-joint gasket 160BHN.
But flanges ASTM A182 F316L does not have a hardness requirement.
So how can I know the difference of hardness between the...
moideen: I mean "thermal condutivity".
Is it the same material? I don't know, that's why I said:
I don't quite understood what you meant whit "same roof/wall".
I'm going to guess that they have the same area, but have different materials.
If they have the same material, makes no sense to change...
This U value is the thermal transmittance, it depends on the thickness and the thermal condutivity. If the software is only showing you the U value, it is already taking the material and thickness into account.
U = t/lambda t: thickness; lambda: thermal condutivity
Q=U*A*deltaT...
Thanks guys!
Frankly just the fact that you didn't found a saddle wihtout ribs something absurd was allready helpfull.
I guess I'll just recommend to include ribs in the design, it's not like it'll require a lot of added material or manpower to do it. Then, I'll do the calculations considering...
Hello,
I'm new in this site and at this kind of work. But I was asked to verify some calculations of a pressure vessel design.
The design is of a horizontal water boiler with 1500 l capacity (800mm radius) and 4,0 kg/cm2 pressure.
I'm researching the subject, my main sources are ASME Division...
