"How it works" has some very strange statements
The first paragraph of "How it works" says:

> Because the oil pushes up against the inside wall of the pipe, the pipe pushes the oil back down causing a swirling of turbulence to occur which creates a drag force. When the polymer is added, it interacts with the oil and the wall to help reduce the contact of the oil with the wall.

Concerns:


 * 1) The pressure of the oil against the wall has nothing to do with turbulence and drag
 * 2) The polymer is fully mixed with the oil; it doesn't materially reduce the amount of oil contacting the wall

Someone with some expertise should rewrite this. -- Dan Griscom (talk) 12:40, 10 September 2022 (UTC)
