In your post you claim : “The AOT is always been shown situated close to the output side of several 3500 hp centrifugal pumps which can be easily calculated with a Reynolds’s number equation as being turbulent (>2000) Very little argument on that fact…slowing the flow down would defeat the purpose of using AOT in the first place and adding more chambers was just to accommodate the volume of flow so it’s didn’t roadblock the line!”
You like to talk about the Reynold’s number, I have something new for you to think about. Something for you to consider before making statement like the one quoted above. It is Poiseuille’s law.
‘For a specified flow rate, the pressure drop and thus the required pumping power is proportional to the length of the pipe and the viscosity of the fluid, but it is inversely proportional to the fourth power of the radius (or diameter) of the pipe.’
‘As I See It’ gave you an example, to help you understand.
“If we use the TransCanada XL pipeline AOT installation as an example we can see the real story. The TC pipeline had a 36 inch diameter capable of moving 830,000 bpd. To accommodate that size line a skid of 4 AOTs was installed. Each of the four AOTs has an inside diameter of 36 inches. The whole point of installing multiple AOTs after each pumping station was to slow the flow of oil inside the AOT to allow adequate time for treatment to be effective.”
To be brief, according to Poiseuille’s law, the pumping power requirement for a piping system can be reduced by a factor of 16 by doubling the pipe diameter or even better in the case of the TC 36 inch pipeline adding a skid of 4 AOTs (36 inches each) to receive the incoming flow.
I am not going to explain how Poiseuille’s law applies, I will let you do the thinking. You should come to the conclusion that you need to study fluid mechanics more before posting your ideas.
