Extension of the tide basins.
.1 The area of a tide basin may be of about one hundred kilometers, up to thousands of kilometers.
.2 Between the smallest tide basin of the North Sea, and the largest one in the Pacific Ocean, there is a ratio of the order of 1:40.
#25 - The time taken by a tide wave.
.3 However, the times a tide wave takes to do a complete tour around the central point, and also along the edge of its basin, are independent with regard to the vastness of the basin in question.
.4 Indeed, the times taken are equal to the cadence of the cycle in the basin considered (either diurnal, or semi-diurnal).
.5 That is, it takes either around 24,81 hours (if the tide cadence is diurnal), or around 12,4 hours (if semi-diurnal).
Constraint #5.
.6 The time for a tide wave to complete a cycle within the area of its basin, does not conform to the extension of that basin, but to the cadence of its generation cycle (diurnal, semi-diurnal).
