In an open channel flow, the discharge corresponding to critical depth is ___________
AMinimum
BMaximum
CZero
DAverage
Answer:
A. Minimum
Read Explanation:
Critical depth is the depth of flow corresponding to minimum specific energy at the section, where the Froude number is 1, energy is minimum, discharge per unit width is maximum, and force per unit weight of water is minimum. In an open channel flow, the discharge corresponding to critical depth is maximum.
