I would recommend using an actual tank model; there are three
vertically cylindrical tank models in the TRNSYS standard library, one
of which allows the volume of liquid in the tank to vary with time.
There are horizontally and vertically cylindrical, spherical, and
rectangular models in the TESS Library. It is a bit harder to deal with
open tanks; the best bet there might be to look at using the Transsolar
pool model although it neglects energy loss from the sides of the pool.<br>

looking in to a project for which we need to
model tanks of liquid (probably oil) within a space and calculate the
heating
required to keep the oil at a set temperature. Would it be possible to
model
this tank as a room? Is there a way that the properties of the air in a
room
could be changed to that of oil while any surrounding spaces would have
normal
air properties? Or do you think a more simplistic model would be more
appropriate?<o:p></o:p></span></font></p>
