Tank
#1 Is just over half full. There is
a defined line and a 1 degree surface temperature difference
between the upper half and lower half. The surface with
no fluid behind it heats quicker than the insulated surface
that has fluid behind it.
Tank
#5 Is in the process of being filled.
There is a 10 degree surface temperature difference between
the empty space and the filled space. The 10 degree difference
is due to the heated fluid as it fills the tank.
Tank
#3 & 4 are full. The surface temperatures are
uniform, as if they were insulated. The solar load from
the sun is absorbed and dissipated into the liquid over
all surface areas uniformly.
Tank
#2 Is the telltale. Tanks like these are constructed
of overlapping sheets of metal. Where the metal sheets overlap
it doubles the thickness of the tanks skin, with nothing
inside to insulate it, the areas where the sheet metal overlap
take longer to dissipate the heat from the sun, allowing
us to see the warmer overlapping joints. If tank 3 and 4
were empty we would see the joints. Those tanks are overall
uniform allowing the conclusion they are insulated (Full).
Look
at the pole and the temperature difference between the right
side and the left side. Now what side do you think the sun
is shining on?
