Piercing the surface with a pencil point creates a wedgelike downstream wave of included angle 35°. Estimate the velocity V of the water. Pebbles dropped successively at the same point, into a water channel flow of depth 42 cm, create two circular ripples, as in Fig. P10.6. From this information estimate (a) the Froude number and (b) the stream velocity.

From this information estimate (a) the Froude number and (b) the stream velocity. An earthquake near the Kenai Peninsula, Alaska, creates a single “tidal” wave (called a tsunami) which propagates south across the Pacific Ocean. If the average ocean depth is 4 km and seawater density is 1025 kg/m3, estimate the time of arrival of this tsunami in Hilo, Hawaii. Equation (10.10) is for a single...
