To calculate the discharge through the circular channel, we can use Manning's equation, which relates the flow rate (discharge) to the hydraulic radius, channel slope, and Manning's roughness coefficient.

The formula for Manning's equation is:

Q = (1/n) * A * R^(2/3) * S^(1/2)

Where:
Q = Discharge (flow rate)
n = Manning's roughness coefficient
A = Cross-sectional area of the channel
R = Hydraulic radius
S = Channel slope

Given:
Perimeter of the circular channel section = 18.84m

To find the cross-sectional area of the channel:
Circumference of the circular channel = Perimeter = 18.84m

Circumference of a circle = 2πr
18.84 = 2πr
r = 18.84 / (2π)
r ≈ 3m

Cross-sectional area of the circular channel = πr^2
A = π(3^2)
A = 9π

To find the hydraulic radius:
Hydraulic radius (R) = A / P
R = (9π) / 18.84
R ≈ 0.477m

Given:
Bed slope (S) = 1 in 1500

To convert the slope to decimal form:
Slope (S) = 1 / 1500

Given:
Manning's roughness coefficient (n) = 60

Now, substitute the values into Manning's equation:

Q = (1/60) * (9π) * (0.477)^(2/3) * (1/1500)^(1/2)

Calculating this equation will give us the discharge (flow rate) through the channel.

Q ≈ 53.62 m^3/s

Therefore, the correct answer is option A: 53.62 m^3/s.
