An irrigation channel of trapezoidal section, having side slopes 3 horizontal to 2 vertical, is
to carry a flow of 10 cumec on a longitudinal slope of 1 in 5000. The channel is to be lined for which the value
of friction coefficient in Manning’s formula is n = 0.012. Find the dimensions of the most economic section of the
channel.
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
