Problem 1. (10 points)-For each question, choose the correct answer from the multiplechoice list (10 points: 2 points each): (1) A hydraulic jump is formed whenever flow changes from (A) subcritical to supercritical flow; (B) supercritical to subcritical flow, (C) laminar to turbulent flow. (2) The two conjugate (sequent) depths of a hydraulic jump have (A) the same specific energy; (B) the same Froude number, (C) the same specific force (3) A falling water surface profile occurs only in (A) Zone 1, (B) Zone 2, and Zone 3. (4) In supercritical flow, as the depth of flow increases, the specific energy (A) increases, (B) decreases, (C) keeps constant. (5) Manning Equation is valid (A) only for uniform flow; (B) only for gradually varied flow; (C) for both uniform and gradually varied steady flow.
