Pipe Flow Calculations Forum

You are right.
you can try also orifice free calculator

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...

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/past...

Have you tried orifice plate calculator?

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.

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.

I would suggest you to try with pressure drop calculator at:
pressure drop calculator.

For pressure p1 and p2 use water column elevation unit in m of water.

For minor losses coefficient - K use calculator included for K.

No it can't be right.

P in that formula is power of boiler 24 kW which I used as possibile one. If the power of your boiler is different also flow rate will be.
For example - for 38 kW it is Q = 3600 * 38 / 33600 = 4.07 m3/h
