Okay, I think I know where I went wrong in my analysis. When I was thinking about this I was using the following term for dp/dz:
$$\frac{\partial p}{\partial z}=\frac{P_2-P_1}{z}$$
Where P_2 is the downstream pressure and P_1 is the upstreamHowever, this is only valid for laminar flow in a...
This is not a homework problem but a thought experiment I am having due to a setup I saw in real life. In the setup there were pressure gauges a little bit to the left and little bit to the right of the pipe in question so that one could measure the pressure drop. In practice the pipe in...
Hi, I would like some guidance about a piping problem I have.
I would like to know how to solve this shear stress equation for a narrowing pipe. This equation gives the shear stress on the edges of a cylindrical piece of fluid having radius r and length L within the pipe. I would like to know...
