Final answer:
a) The Manning Equation
The equation often used to predict the flow in open channels is The Manning Equation. It is used to calculate the average velocity of water flow in an open channel based on factors such as roughness, slope, and cross-sectional area of the channel.
Step-by-step explanation:
The equation often used to predict the flow in open channels is The Manning Equation. It is used to calculate the average velocity of water flow in an open channel based on factors such as roughness, slope, and cross-sectional area of the channel.
The equation is given by:
Q = (1.49 / n) * (A * R2/3 * S1/2)
Where:
Q is the flow rate in cubic meters per second
n is the Manning's roughness coefficient
A is the cross-sectional area of the channel
R is the hydraulic radius
S is the slope of the channel
