6.2. notes#

Relative differences are greater than 2% for \(t=400.s\), lower for \(t\ge 600.s\)

The maximum difference observed between two knots on the surface, in relative and absolute terms, is 0.012% or \(\mathrm{0,055}°C\), between the point \(B\) (\(\mathrm{N56}\)) and the point \(C\) (\(\mathrm{N61}\)) at the moment \(t=400.s\). These differences decrease in absolute value as time increases.
