A channel carries a discharge of 5 cumec with a flow depth 1 m. The side slopes are 1 to 1 and
bed slope 1 in 3520. Find the bed width and the velocity. The values of Chezy’s C for this channel for different
values of hydraulic radius R are as tabulated below
| Hydraulic radius | 0.7 | 0.8 | 0.9 | 1.0 | 1.1 | 1.2 | 1.3 | 1.4 |
| Chezy’s C | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 |
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
