10.1 On a distant planet small-amplitude waves travel across a1-m-deep pond with a speed of 5 m/s. Determine the acceleration of gravity on the surface of that planet. 10.2 The flowrate per unit width in a wide channel is q2.3 m²/s. Is the flow subcritical or supercritical if the depth is(a) 0.2 m, (b) 0.8 m, or (c) 2.5 m? 10.3 A rectangular channel 3 m wide carries 10 m³/s at a depth of2 m. Is the flow subcritical or supercritical? For the same flowrate,what depth will give critical flow?
