Resistance to uniform turbulent flow in an open channel system is often expressed in terms of the resistance co-efficient using
A. Manning’s equation
B. Chezy’s equation
C. Darcy -Weisbach equation
D. Bernoulli’s equation
E. Francis Formula
Choose the correct answer from the options given below:
Show Hint
Manning's \( n \), Chezy's \( C \), and Darcy-Weisbach's \( f \) are the three standard resistance coefficients used in open channel hydraulics.
They can be related to each other mathematically:
\[ C = \frac{R^{1/6}}{n} = \sqrt{\frac{8g}{f}} \]
