Background
Modeling is about translating an engineering problem into
asimulation problem. Once translated, the simulator does allthe
calculations.

Key Teaching Points
To calculate the maximum fill up of a propane tank, we need
to know the ratio of the mole volume of the saturated
liquidpropane at 25 C to that at 58 C.
This ratio is the same as the ratio of the density of
thesaturated liquid propane at 58 C and that at 25 C.
The feed stream represents the saturated liquid propane at25 C.
The liquid product from the Heater block representsthe saturated
liquid propane at 58 C.
Use of a Spreadsheet includes the following steps: Access
flowsheet variables.
Link flowsheet variables to cells on the spreadsheet.
Define customized calculations in the spreadsheet.

Recommended Further Exercises
Calculate the maximum % fill up for a water bottle.
Thetemperature of the bottle can change from 25 C to 58C. Assume
that the pressure inside the bottle is 1 atmbefore and after the
temperature change.
