I believe that the subject paper is the original publication on the "stream analysis method". I want to review this original, and historic work. If you are interested in selling your copy, please let me know?
Thanks for your help.
I am looking for a copy of the following paper -
Palen, J.W. and J. Taborek, "Solution of shell side flow pressure drop and heat transfer by stream analysis method", Chem. Eng. Prog. Symp. Series 65, No. 92, 53-63, 1969.
Can anyone help me?
Compress provides calculations for support lugs with double gussets.
Are there any plans to add the capability to analyse support lugs with single gussets?
I agree that the sizing calculations for full strength welds should include U-Tubes. The sizing formulas provided by the Code applies equally to U-Tubes. If the Compress user selects "full strength welds", then the sizing and calculations should be provided.
Please correct me if I am wrong?
I suggest that you look at ASME section VIII, division 2. This code uses stress intensity to define allowables. As you know this code is for pressure vessels and not for building structures. But, the allowable stress intensities which are tabulated ASME section II are applicable to the stress...
When gas or vapor is flowing through an orifice, a situation can exist when the flow rate would not be increased if the downstream pressure is decreased ( while the upstream pressure remains constant). When this happens, the flow rate through the orifice depends on the upstream pressure, but is...
I agree that if you use the method that calculates the equivalent pressure and then compares the result to the flange rating, this analysis is very or perhaps too conservative.
A less conservative, but acceptable approach would be to calculate the equivalent pressure and then used this pressure...
sme75,
I have been using this formula for years and I am almost certain that I checked it out before I first used it (to calculate vacuum rating of tanks). But, since you ask the question, I went through the derivation again!
If you are very careful with converting inches to feet and psi to psf...
The allowable vacuum pressure for an API 650 tank is 1 inch water, and it is 1 oz per square inch for API 620 tanks. If additional vacuum rating is desired, then calculation should be performed to verify that the structural integrity of the tank is sufficient for the desired vacuum.
Generally...
See Maan H. Jawad. James R. Farr,"Structural Analysis and Design of Process Equipment",2nd ed.,John Wiley & Sons, page 468. The formual given in this reference is the basis for the formula provided by API 650 for placement of stiffners on the tank shell. Therefore this is the formula...
ASME Section VIII vessels (15 psig or greater design pressure):
A relief device is required whenever there are credible scenarios that could cause the vessel pressure to exceed 110% of the design pressure.
A relief device is required to protect the vessel during an external fire if an external...
