LOSS OF HEAD IN GRATINGS

PERDIDA DE NIVEL EN REJAS

A theoretical study is presented of the design of drainage and manholes in gullies and highway ditches, which makes it possible to obtain tables of results dealing with the problem of the flow of a liquid flowing in a free channel through a grid of metal bars. The design of drainage and of manholes in highway ditches is studied. The analysis is based on the inclination of the grid with respect to the horizontal and geometrical section of the bar, and is not Dependent on the dimensions or the spacing. (TRRL)
