cross section is rectangular with depth

equal to one half its width.

 

Choices: A.) 0.00197 B.) 0.00781 C.) 0.00241 D.) 0.00167 E.) 0.00185

 

B. Determine the required slope if the

channel is a semi circular section.

 

Choices: A.) 0.00197 B.) 0.00781 C.) 0.00241 D.) 0.00167 E.) 0.00185

 

C. Determine the required slope if the

channel is trapezoidal with depth equal

to the width of the channel bottom and

side slope of 1:1

 

Choices: A.) 0.00197 B.) 0.00781 C.) 0.00241 D.) 0.00167 E.) 0.00185
