Question 1

What is the main equation for calculating discharge over a rectangular notch?

Q = (1/2)Cd * b * sqrt(2g) * H^2
Q = (2/3)Cd * b * sqrt(2g) * H^(3/2)
Q = Cd * b * H * sqrt(g)

💡 Hint: Remember the power of H in the equation.

Question 2

True or False: The discharge coefficient (Cd) is always equal to 1.

True
False

💡 Hint: Consider how conditions might alter the coefficient.
