What are the most economical dimensions for a rectangular brick channel designed to carry 10 m3/s of water with a uniform flow? Use n= 0.015 and S=0. 001.

Choices:

A. b = 4.32 m, d= 2.15 m

B. b = 3.28 m, d = 1.64 m

C. b = 2.92 m, d = 1.47 m

D. b = 3.86 m, d= 1.91 m

Water flows in a trapezoidal channel and running full. If the channel has a discharge of 8.0 m^3/s, find the base width for the most effictent section. Use n= 0.012 and S = 0.0008.

Choices:

A. 2.66 m

B. 2.33 m

C. 1.77 m

D. 1.53 m
