Tidal currents in narrow channels connecting coastal bays with the ocean can be very swift; water must flow into the bay as the tide rises and back out to the sea as the tide falls. Consider the rectangular bay shown in Fig. 16-34a. The bay is connected to the sea by a channel 190 m wide and 6.5 m deep at mean sea level. The graph (Fig. 16-34b) shows the diurnal variation of the water level in the bay. Calculate the average speed of the tidal current in the channel.
