1/1/2004, · For convenience, Table 4.1.2 tabulates wind pressures for various wind speeds with Cs = 1.25 and Ch = 1.0. Height is the vertical distance from ground or water sur- face to the center of area. The shape ,coefficient, C for a derrick is assumed as 1.25. Cs, and Ch were obtained from ABS, "Rules for Building and Classing Offshore Drilling Units, 1968."

The effect of ,hydraulic diameter, on heat transfer and pressure drop is illustrated in Figures 1.2 and 1.3 for water and air flowing in a square channel under constant heat flux and fully developed laminar flow conditions. The heat transfer coefficient h is unaffected by the flow Reynolds number (Re) in the fully developed laminar region.It is given by:

Therefore, as an independent dimension of channels with internal flow, use is made of an equivalent ,hydraulic diameter, D H characterizing the relation between the cross-sectional are and the wetted perimeter P: D h = 4S/P. DH is chosen such that the ratio of pressure forces, acting on the flow cross section, to friction forces, applied along the channel perimeter of arbitrary shape ...

Hydraulic diameter - Wikipedia
Hydraulic diameter - Wikipedia

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 ...
