Design of Pressurized Vaulted Rectangular Conduits Using the Rough Model Method (Part 2)

Abstract:

The problem of calculating the diameter of a pressurized vaulted rectangular conduit is solved explicitly through two methods which are based on an referential rough model whose geometric and hydraulic characteristics are well defined. The first method provides a highly reliable approximate relation which gives very accurate results for all practical applications. The second method consists in introducing into the calculations a rectangular rough model whose geometric and hydraulic properties were judiciously chosen. The theoretical development leads to an equation of third degree whose resolution has been made possible by the hyperbolic and trigonometric functions. Practical examples are presented to explain the procedure of calculation.
