Greetings everyone,
I've always found my questions on google take me to this website. So I thought why not join them?
I'm a petroleum engineer working as a production engineer and I'm mainly interested in fluid mechanics and fluid flow in porous media.
I've already had a wonderful discussion...
Appreciate the immense help, Chestermiller and Delta^2.
I'll do some research on the subject and see if I can find something that will get me where I want to get.
Thanks,
Never mind. Apparently, Wikipedia has a good article on drag forces and drag coefficients.
I just would like to know if drag would account for a pressure differential induced by friction.
For example, if the annulus between a pipe and a plug is small enough to generate an appreciable pressure...
These two comments pretty much summarize what I've been asking about. Thank you gentlemen for your patience.
I've tried figuring out the force acting on a fully submerged plug using inviscid theory and when the net force came out as a zero, I thought I was doing something.
Here are the charts...
Delta, I think you're right about the plug being half-submerged.
But allow me to continue to demonstrate with one more example just to be sure.
Here I'm changing the diameter of the pipe such that the upstream velocity and pressure remain the same.
Since the plug diameter, the striking fluid...
Thanks for the information, Chestermiller and Delta. I'm sure the example shown was to demonstrate how to calculate the force acting on the plug and that's why the upstream pressure is a little off.
But my concern is that the method applied to calculate the force acting on the plug does not seem...
Greetings everyone,
I've been recently trying to calculate the forces acting on a stationary object in pipe with flowing fluid. I've returned to my college textbooks to get some help and I've found examples that clearly demonstrated how to accomplish just that.
Below is one example.
This...
