Solution Summary

In first problem, average power which can be produced by using tidal basin water. In second problem group velocity of a given wave is estimated.

Solution Preview

(b) Area of the basin, A= 240km^2 == 2.4*10^8 m^2
mean tidal range, h = 12.4 m
avaerage tidal period, t = 12.5 hr == 12.5*3600 s
Density of water, d = 1*10^3 kg/m^3
g = 9.8 m/s^2

Potential energy due to, tidal:
U = m*g*h/2
= (d*A*h)*g*h/2
= ...
