Fuel evaporation in a tank - Pressure calculation

Main Question or Discussion Point

Hello everybody,

I have the following problem:

I have a fuel tank, with a liquid phase (the fuel) and gas phase at To and P0, where T is temperature and P pressure. I assume that the gas phase at the instant t=t0 is air.
(Is this assumption correct?)

The temperature of the liquid phase varies over the time with a certain profile from T0 to Tend.
The fuel due to the increasing of the temperature evaporates with a certain law (most probably unknown).

How can I calculate the equilibrium pressure between the two phases according to the temperature changes over the time?

Thanks in advance,
K

Welcome to PF!

I would think you wouldn't calculate it but rather just look up the vapor pressure in a table of the fuel's properties.
