Drag Coefficient for a Hollow Cylinder
Drag Coefficient for a Hollow Cylinder
(OP)
Can anyone tell me the drag coefficient for a hollow cylinder through a fluid?
The fluid in question is viscous (50+ cP for the purposes of calculations) and incompressible with a density of 1800 kg/m^3. The cylinder is 30.5cm long with an inner diameter of 7cm and outer diameter of 8.9cm. Velocity is in the range of 14 to 15 m/s.
I'm afraid my rather basic fluid mechanics text, just doesn't have info on a hollow cylinder.

That is to say that the fluid is flowing through the hollow portion and around the outer diameter.

Remember, first define the problem, then solve it.
