On a tower there is a 14" feed nozzle in the cone section. The pipe runs all the way down to the bottom. About 60 feet. Now, the flow is 2 phase and the pipe is going to be vibrating. What precautions do I need to take , what analyses do I need to make to properly secure the pipe to the vessel...
I have a 15 foot long, 6 foot ID vessel. Initially the saddles were symmetrically placed at D/4 from right and left tangent lines. Latter due to nozzle interference issue, I moved right saddle in by 1 foot thus reducing saddle to saddle separation by 1 foot. The left saddle was not moved. Is...
WRC 107 talks about two stress concentration factors.
Kn is membrane stress conc. factor (pure tension or compression)
Kb is bending stress conc. factor
But can some one tell me how and where to look them up?
I have a horizontal drum with liquid inlet on the left end on the shell. Outlet with V breaker is on the right to the bottom. There are 2 level gauge nozzle on the shell, 2 level transmitter nozzles on the shells. Are there any guidelines for locating those nozzles? I guess they need to be on...
I was looking at a data sheet for valve + actuator for flow control. Pneumatic actuation. The data sheet specified Air consumption (6.7 cu inches etc. ) for different models. How is air consumption defined for this application? Is it the amount of air reqd. per actuation? At what pressure do I...
We are having some trouble placing vacuum ring on a tower. We are using ASME Section VIII Div 1. We looked in appendix 1-8C, 1-8E and found that the max distance of the centroid of the vacuum ring from the center of the seam weld is 0.84". Since it is RT-1 radiography, we got to radiograph the...
I am using ASCE 7-2002 seismic code for design of a horizontal vessel. I am using DISASU software. Can someone tell me what the following parameters mean?
Sds, I, R
In the data book given to me, I need to use the following parameters. Ss=0.20, S1=0.08, I=1.25, Soil Type= +D. How do I translate...
I work at an engineering firm. Lot of documents, drawings need to be reviewed internally. They go from one person to next and often it will be nice to track a package internally (Idea is similar to tracking a FEDEX package) But in my case the scope is small. The tags will need to communicate...
one gas source in the center of a huge cylindrical steel storage tank. this gas is heavier than air. I want to do some quick calculations to find out how much gas will leak out of the structure and how much of it will stay. There are going to be effects of wind entering the tank through vents at...

I am thinking of a new ambitious project with our freezers. We have a spiral freezer to freeze meat patties. I want to increase the throughput through this freezer. What have is ammonia refrigeration system. I have space limitations and the total size of the freezer can not be increased. I was...
