List of hydraulic diameters - db0nus869y26v.cloudfront.net

The ,hydraulic diameter,, D H, is a commonly used term when handling flow in non-circular tubes and channels. Using this term, one can calculate many things in the same way as for a round tube. It is defined as =, where A is the cross-sectional area of the flow, P is the wetted perimeter of the cross-section.. More intuitively, the ,hydraulic diameter, can be understood as a function of the ...

They are often used in vertical ,wells, as there is near zero deviance in annular space about the tool. Rigid centralizers are slightly smaller than the well bore. They are more commonly used in deviated or horizontal well bores where the weight of the casing string would cause a bow spring centralizer to experience eccentric compression which could jeopardize the seal.

The coefficient C D depends on the shape of the float and the Reynolds number (based on the velocity in the ,annulus, and the mean ,hydraulic diameter, of the ,annulus,) for the annular space of area A 2. In general, floats which give the most nearly constant coefficient are of such a shape that they set up eddy currents and give low values of C D .
