P10.4 P10.6 P10.7 Water flows rapidly in a channel 15 cm deep. 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.

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...
