- When subcritical flow goes over a step down, does the kineticenergy increase, decrease or remain constant?

- You have subcritical flow going through a channel constrictionthat does not influence upstream water levels. If the criticaldepth is observed in the constriction, the minimum specificdischarge is passing through the constriction
True or false?
- Subcritical flow encounters a step up transition that issmaller than the maximum step height. Does the specific energy:
increase
decrease
remain the same
- In supercritical flow that does not encounter a hydraulicstructure, the upstream water is influenced by downstreamconditions.
True or False?
