    Pipe Speed Water
AI Thread Summary
To calculate the speed of water at a specific point in a pipe, the cylindrical Navier-Stokes equation should be solved with the correct boundary conditions. The assumption that all water at a given radius moves at the same speed is valid, but it is not directly related to laminar flow. The discussion emphasizes the importance of applying the right mathematical framework to obtain an accurate analytical solution. Understanding these principles is crucial for fluid dynamics in pipe systems. Accurate calculations can lead to better predictions of flow behavior.

Hi

I was wondering how to calculate the speed of the water at a cetain point in the pipe

(i assume that all the water at that radius is going at the same speed due to laminar flow)

Yes it will be going at the same speed. No it has nothing to do with laminar flow.

You just solve the cylindrical Navier-Stokes equation with the appropriate boundary conditions and you will have a nice analytical answer for your profile in the pipe.

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
