Hi! I am trying to find the equation for Propane evaporation rate in small pressurized steel tanks (10#~60# tanks). I know that it is a function of the wetted surface area of the tank, the ambient air temperature, and the humidity, but I can't find an actual equation to use. I've done quite a bit of research on Google, but I can't seem to find anything. Can someone out there help me?

Thank you, thankyou!
