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.
