I think the pages thing is his it works so that you don't download all the posts so it's faster.

There is entry loss at the higher tapping point,. It does not remain a pipe ID sized column of liquid dies it? Entry loss is entry loss. The static head is what makes P4 higher than P3.

Good, That's much better than wrecking the items or giving someone a bad back. Thanks for letting us know

Thermal relief is a relatively small amount but you need to be able to quantify the amount, if any, which returns tot he tank after it has been metered. An unscrupulous operator could divert lots of product back to the tank. So you might get pulled up if the system is audited by a customer or...

I don't know without doing the numbers, but by instinct using one cylinder after another would be better. By 6m3 I thought you meant an actual volume of 6m3. Nitrogen cylinders typically are 49 litres at about 150 bar (2100 psi) If you can get 200 bar, that's a big difference so make sure you...

Often a fitting is forged to allow for any thickness of connecting pipe schedule by machining what you want. This seems to have been a manufactory error. Remember - More details = better answers Also: If you get a response it's polite to respond to it.

You need to look at this either as a series of bottle use or linking all together. Use some or mass to figure it out. That's a very big cylinder though. Are you sure? So if all you have is the cylinder pressure then you will not be able to use all the nitrogen in the cylinder. To use it all...

Tried "Leca"? E.g. https://www.cpa-horticulture.co.uk/leca?gad_source=1&gclid=Cj0KCQjw4Oe4BhCcARIsADQ0csk-ms5IZZLNTjrQQGW5x35lTWG_QI4XQbYRjO36ZsWNXezEjT_ZQSwaAv28EALw_wcB Can you provide more information on what you mean by polystyrene aggregate as it's not clear if you mean the really...

SO what is the pump mounted on exactly? If just placed on a thin metal ceiling then it needs more support as indicated. Drawing, photo etc would help, but it sounds a bit of a strange thing to do (mount it on a ceiling with no additional support). Remember - More details = better answers...

tonbaldin. You keep talking about "low flowrate" but without a measurement of the flow rate how do you know? This is a small system so pressure drops are going to be low, despite "high velocities" I'm still of the opinion that you're running off the end of the curve on the RHS and basically...

No I don't think it is practical because at the thick end of the cone your OD remains the same. So your insert ( not really shown on your sketch) would be infinitely thin at the thick end. Practical thickness needs to be a certain value (1mm? or more?). You really need to amend your sketch to...

In my opinion this is what you need to do. Unless you have multiple eye bolt connections to allow you to lift the RD off the bottom flange then you won't be able to re instate the disc without destroying the gasket. Essentially as the Obturator says, Removal is the reverse of installation...

"High Quality" and "Best Industry Practice" are very difficult things to judge and determine in a court, which is only where this would potentially end up. But if you're confident that this is what you do, then I don't see the point of making a fuss unless it increases your insurance premium...

By slip ring so you mean spacer?? Thickness seems relatively irrelevant as there are no significant forces which thickness impacts. ID and OD should match the connecting flange up to the inner diameter of the bolt circle. Ask the purchaser is my only thought. Remember - More details =...

P is pressure. Q is flow. Remember - More details = better answers Also: If you get a response it's polite to respond to it.

Sketch 1, P 1, 2 and 3 are essentially the same. If these are centrifugal pumps it's easy for one pump to back out the second it be 90/10 in terms of flow. You need to know the pump curve very well. All you can say about the second is that the flow will be whatever goes through P1. P2 will...
