Thanks for the above replies. I will try and re-word part of the question. If I had the above tube with the same defect being constantly fed (failure has gone unnoticed,compressor keeps running) with the normal gauge pressure being 150psi how long would it take for it to be classified as a...

Good Afternoon, I am looking to work out the volume of gas lost in a fractured tube line. If I have a tube that measures 12mm outer diameter with a 1.5mm wall thickness giving a 9mm internal diameter that has a gas going through it at 150psi which develops a 1mm hole how would I calculate the...

Good Evening, I am looking for a bit of help and I am hoping this forum will be able to provide it. I have an issue with instrumentation tubing at the minute where I believe that the area of the orbital weld internally is starting to suffer from pitting corrosion. To start off with the welds...

Yes i know that was a typo mistake from a previous calculation i was doing for tube in inches and what i wrote the example from.

I have mike but i am not very trusting and wanted to check the initial calculation was correct.

Thanks for all the replies. At least i know i have the calculation correct and i can now go on and calculate for the various flushing fluids and tube sizes i use. I hadnt taken into account pressure drop as the runs i am involved in are at the most 4-5m in length. Does anyone know off any...

Good Evening, I am trying to work out the litres per minute required to flush a length of 10mm O/D tubing with 1.5mm Wall Thickness. I know I need to achieve a reynolds number of 4000 to flush it. I calculated it as below but I think it may be wrong: 1. Find out fluid kinematic viscosity at...

LittleInch thanks for the responses. I'll have a read over your post again, look at my calculations, re-calculate and I may be back to ask further questions but again thank you for your help.

Thanks for the answers. I wouldn't say I have bitten off more than I can chew but I will admit I am still learning the finer details. But if your not learning your not doing anything. The 15m/s^2 I gained from the spec sheet for the hose. It stated max flow velocity as that. I am willing to...

Good Evening, I have been trying to work out the size of pump required for an upcoming pressure test project. I followed the below but think the pressure drop I have calculated is far to large and is now a sticking point for me deciding on pump size. I just want to see if anyone on here can...

Hi all I am new here and have just done a search to see if I could find any posts on winglets. Although I did find and read the post they did not really answer my question. My question is how has fitting blended winglets affected the basic flight performance of an aircraft in the glide and...
