A very wide rectangular channel is designed to carry a discharge of 5 m³/s per meter width. The design is based on the Manning's equation with the roughness coefficient obtained from the grain size using Strickler's equation and results in a normal depth of 1.0 m. By mistake, however, the engineer used the grain diameter in mm in the Strickler's equation instead of in meter. What should be the correct normal depth? (a) 0.32 m (c) 2.00 m (b) 0.50 m (d) 3.20 m

Question
A very wide rectangular channel is designed to carry a discharge of 5 m³/s per meter width. The
design is based on the Manning's equation with the roughness coefficient obtained from the grain
size using Strickler's equation and results in a normal depth of 1.0 m. By mistake, however, the
engineer used the grain diameter in mm in the Strickler's equation instead of in meter. What
should be the correct normal depth?
(a) 0.32 m
(c) 2.00 m
(b) 0.50 m
(d) 3.20 m
