Thank you Smile AOT works

AOT has an effective effect within the 24 hour range, the flagship pipeline with the 4 skid system mounted moves oil at a rapid walking pace, so it would be safe to think one skid of 4 would not have a material effect on the overall operation of that pipe, a single installation could be used to remove a bottle neck, but the language used by STWA is that bottle neck removal is a secondary benefit, so I would be quite confident that price paid for the first unit would have taken into consideration a full deployment and the overall cost and for this to not just be financially viable, but also significantly more profitable for that company.



This comment bring me back to a discussion I had with "Alkalinesolution1" back in November 2013. The issue was ; will the flow rate increase with just one AOT or do we need AOTs at every pumping station along the full length of the pipeline?
"Alkalinesolution1" contacted Dr. Tao and was given the following information (Post #6207 & #6212)

I received this confirmation directly from Dr. Tao, in an email.

He said that:
1) the total pressure is the sum of the Delta P (pressure drop) of each section
2) if you reduce the pressure drop in one section, you reduce total pressure as well
3) power is total pressure * flow rate Q
4) so if you reduce pressure drop in one section, you reduce total power
5) however the equation cited is only for laminar flow, and does not apply to a turbulent flow. But the pressure drop question is still the same. There are other equations for determining the situation in turbulent/laminar flow scenarios.



I agreed with that, but then "Alkalinesolution1" says

In conclusion, for everyone who has been confused by the science mumbo jumbo: if you put the AOT in the middle of a section of pipeline, you get increased flow. If you put another AOT on, you get more increased flow. If you put AOTs all the way along, you get still more increased flow. One section of treated oil in a pipeline will give you some benefit, and more AOTs will give you more benefit.



I do not agree that you get increased flow each time you add an AOT, unless you add AOTs the full length of the pipeline at each pumping station. But you do get some benefit in terms of the pressure drop requiring less power to move the oil.

See post #6212

Is kind of true (actually the equation is Q=VA), but not germane to the question at hand. Nothing says that Q is the same for both sets of conditions. If you do set Q to be equal for both sets, then yes velocity is the same, but all we're suggesting is that the power required to push Q down the pipes is less if the viscosity of at least one of the sections is reduced.



Any time a liquid is asked to change direction or to change velocity there is a change in energy. The energy lost by the liquid is converted to heat created by friction. Since the amount of liquid exiting a pipe has to equal the amount entering the pipe (conservation of mass), the velocity must be equal. If the velocity is equal, then the velocity energy (head) must be equal. This only leaves one place for the energy to come from; pressure energy. The measured pressure entering the pipe will be higher than the measured pressure exiting the pipe.

See my post #6166 : Factors that affect Head Loss

I think it is only fair the we acknowledge that Mr. Sano did see clear in his post #6213
