Question
Select the true items related to specific energy and critical flow. Select only the four correct answers. Avoid random selection as each incorrect selection will be penalised by imposing negative marking. 0 For a given depth, there are two possible specific energies 0 The state of flow denoted by Froude's number greater than one is called subcritical flow Critical flow corresponds to unit Froude's number 0 The velocity corresponding to minimum specific energy is called the critical velocity 0 0 The state of flow denoted by Froude's number greater than one is called supercritical flow Critical flow corresponds to unit flow velocity 0 For a given specific energy, there are two possible depths The velocity corresponding to minimum specific energy is called minimum velocity

Expert Solution
Step 1: Statement 1:

Statement 1 is false, Because from the depth vs specific energy graph, we observe that for a given specific energy there are two possible flow depths(y1 and y2)
