Re: Vacuum Relief Valve Sizing

You must know how "quickly" it is in order to calculate flow rate of air required and pipe diameter needed for it. When you know time t that is needed to drop temperate from one point to another you can calculate how much volume ( V ) is changing in that time and from there you have flow rate (Q=V/t...

Re: velocity to pressure??

How is you system looking? Do you have one point where two pipes start and air exits to atmosphere? If so than you have two parallel lines with same pressure drop (pressure change) from the start to the finish and for that equal pressure difference two flow rates are established - which you can use ...

Re: Help Please: Viscous Oil Flow Rate

I see... That is non statinary flow as you have pressure change over time so none of calculators availble on pipeflowcalculations.com is covering that problem. But in the near future it would be good to do one as many asks for tool that will solve similar problem. The problem is also that fluids tha...

Re: CYLINDER LEAK DOWN TESTER

Thank you for your data, but I suggested you to use GAS DISCHARGE CALCULATOR and not isothermal just to check from the other point of view.
Your experience with tester for sure will be of interest for others as well as for me also.

First of all try with this to enable copy/paste: https://blogs.oracle.com/kyle/entry/copy_and_paste_in_java_in_java . For some reason copy/paste stopped working in new version of windows web browsers. Also, if you click "report" button all results will open in web page so you can copy/paste from the...

Re: Elevated tank and piping calculation

I checked you data and as flow is laminar (very high viscosity fluid you have) the equation is for laminar flow used. Reynolds number is just 801 so you are in laminar zone.
I think you did it right.

Re: Elevated tank and piping calculation

Here is how you can enable copy/paste o your side:

Also, when you press theory button in calculator web page with used equation will be opened in browser.

I will check your results and tell you more, a bit later.
