This may be a pretty basic question, but I've come across fan curves with the units of 'mm VS' and it's not particularly clear what this is.
mm of water?
VS - is this a combination of Velocity and Static heads?
Thanks
Ladies & Gents,
I'm currently working on a system for removing the sand from water. The pipes are all flowing fully flooded with a small gradient. When looking at sampling the stream, all the references talk about isokinetic sampling being required for gas streams with no reference to it...
We have a scenario where a 2 metre section of 3" pipework (call it 80mm ID) is pressurised up to 150 barg with water. If a quarter-turn ball valve is quickly opened (assume that it 0.25 seconds to fully open) then what is the maximum velocity that the water can attain in the downstream 3"...
we're looking at temperature build-up in a pump minimum flow recycle loop and I've been reliably informed that the temperature of water will increase when water is depressurised i.e. when letting water pressure down from 100 bar to 30 bar the temperature could increase by 1 degC (I've used...
A point that was raised in thread135-69800 has uncovered the following free webbook on heat transfer

I am sure that it will be useful.
GPSA 11th Edition (SI Units) - Figure 7.4, gives an "Intermediate Law" for the gravity settling of a sphere in a still fluid. This apparently is valid for droplets between 100 and 1000 microns and a Reynolds number of between 2.0 and 500. As a result it lies between the effective...
Mature oil & gas fields inevitably produce sand along with the hydrocarbons and water. These sand particles result in a multitude of problems, one of which is erosion of 90° elbows. Standard practice is to install "Target Tees" at these point.
The blind on the tee generally has a...
Gents,
I'd like your thoughts and comments on the following sizing methodology for an Anti-Syphon Vent.
A swan-neck was installed on the liquid piping downstream of a vessel to ensure that a liquid level was retained within the vessel at all times. The hydrocarbon laden gas from the vessel...
