An open channel is to be constructed of trapezoidal section and with side slopes 1 vertical to Find the proportions (i.e., relation between bottom width and depth of flow) for minimum excavation (i.e., best hydraulic section). If the flow is to be 2.7 cumec, calculate the bottom width and the depth of flow assuming C in Chezyโs formula as 44.5 and the bed slope is 1 in 4000.
Unit weight of materials used in Construction The unit weight of materials is an important factor to consider in engineering and construction projects. It refers to the weight of a material per unit volume, typically
