Which of the following conditions should satisfy for the formation of supercritical flow in an open channel?

Correct option is A

→ When the depth of follow in a channel is less than the critical flow and froude number is greater than 1 it is known as supercritical flow.
→ In subcritical flow the depth of flow in a channel is greater than critical flow and froude number is less then 1.
→ Supercritical flow is also named as torrential flow as shooting flow.
→ Subcritical flow is also named as tranquil flow are streaming flow.
→ Froud's number is 1 for critical flow.
