May 25, 2020The formula for wind load is F = A x P x Cd x Kz x Gh, where A is the projected area, P is wind pressure, Cd is the drag coefficient, Kz is the exposure coefficient, and Gh is the gust response factor. This formula takes a few more parameters into account for wind load. This formula is generally used to calculate wind load on antennas.ALLOWABLE PIPE SIZE, CLASS AND MATERIALS FOR a design factor or safety factor is applied during the design of the pipe wall dimensions, (design factor can vary from 1.25 to 2.1 depending on the type of PE pipe design resistance againch external loads eg The DN values shown without reference to a pipe material (eg PE) refer to the inside diameters of the pipe while the DN marked PE etc are the external diameters.

For buried pipe embedded in soil, axial displacements are resisted by friction that develops on the pipe-soil interface. Frictional resistance is mobilized as the pipe moves axially and is fully mobilized at locations along the pipe where the movement is sufficient to cause the pipe to slip through the embedment.
