Dimensions of Irrigation Canal:
To determine the dimensions of the irrigation canal, we can use the Manning's formula which is given as follows:
Q = (1/n)A(R^2/3)S^1/2
Where,
Q = Discharge (m^3/s)
n = Manning's roughness coefficient
A = Cross-sectional area of the flow (m^2)
R = Hydraulic radius (m)
S = Slope of the bed (m/m)
Discharge Calculation:
Therefore, the discharge flowing in the channel is 0.098m^3/s.
Dimensions of Irrigation Canal:
Therefore, the dimensions of the irrigation canal are 3.7m (width) and 1m (depth).
- B/D ratio = 3.7
- N = 0.0225
- m = 1
- S = 1/4000
- Side slopes of the channel is ½ horizontal to 1 vertical
To determine the dimensions of the irrigation canal, we can use the Manning's formula which is given as follows:
Q = (1/n)A(R^2/3)S^1/2
Where,
Q = Discharge (m^3/s)
n = Manning's roughness coefficient
A = Cross-sectional area of the flow (m^2)
R = Hydraulic radius (m)
S = Slope of the bed (m/m)
Discharge Calculation:
- Manning's roughness coefficient (n) can be estimated based on the type of channel material and its condition. Assuming n = 0.025 for a concrete-lined channel.
- From the given data, B/D ratio = 3.7. Let's assume a depth of 1 meter (D = 1m). Therefore, the width (B) can be calculated as B = 3.7 x D = 3.7m.
- Cross-sectional area (A) = B x D = 3.7 x 1 = 3.7m^2
- Hydraulic radius (R) = A/P where P is the wetted perimeter. For a trapezoidal channel with side slopes of ½ horizontal to 1 vertical, P can be calculated as P = D(1 + 2[(1^2 + 1/2^2)^1/2]) = 5.06m. Therefore, R = 3.7 x 1 / 5.06 = 0.731m
- From the given data, S = 1/4000
- Substituting the values in the Manning's formula, we get Q = (1/0.025) x 3.7 x (0.731^2/3) x (1/4000)^1/2 = 0.098m^3/s
Therefore, the discharge flowing in the channel is 0.098m^3/s.
Dimensions of Irrigation Canal:
- Width (B) = 3.7m
- Depth (D) = 1m
Therefore, the dimensions of the irrigation canal are 3.7m (width) and 1m (depth).
