It is clear to me that API 12F is a pre-engineered standard. It is unclear to me however what the testing requirements are. The standard says to test to 1.5x the design pressure. The design pressure is listed as 16 oz/in^2 or 1 psi. The tank will clearly see 6.5 psi just due to static fluid...
I am interested in calculating the duration of flowing gas (nitrogen, argon, or air) from storage tanks (cylinders, receivers, etc). The purpose is to determine if the demand can be met without changing the tank every day.
For example, I have a tank of compressed nitrogen at 2000psi, that has...
I am evaluating a demo of NEiNastran right now and am pleased so far with what I have accomplished with it. It seems very capable.
I am considering also buying Ansys, likely strucutral depending on the dollar amounts. I am a previous user of Ansys (version 4.1 and 5.3) and did some interesting...
I have some info on a vertical curve. Everything is given, however I do not have reference to the exact nature of the data. The elevations of the start and end of the curve is given as well as the PVI at the middle. The curve is a crest curve symmetric also. I have the following.
2% slope into...
In the process of designing a gas supply line to a multi fuel boiler. I am providing a safety relief system vented to the atmosphere. The supply line is 8". The relief line however I am not exactly clear on what size it should be. It has been suggested that the vent line will be about 2". I am...
Have done a lot of reading over the last couple weeks and am still at a bit of a loss on a couple items. I am in the preliminary design stages of a coke oven gas line and am working at determining the flow rates and pressure drops for the system. The system is relatively short at 70 feet. There...
Hello All
I am in the process of laying out a gas line (coke oven gas, sg=0.36) that has an inlet pressure of only 3.25 psig. The flow is 220 000 SCFH. The dilema I am facing is that the tolerance of the allowable pressure drop is only 0.75 psi, by the end of the run. I am a bit skeptical of...
