Hello, this is my first post, so please forgive me if I am not doing this exactly right. I am working on a problem in which I have an open top cylindrical tank that contains a fluid at a higher temperature than the ambient air temperature surrounding the tank. What I am trying to determine is the rate at which heat is transferred from the tank to the room. I believe this is a multi-faceted problem which requires looking at heat transfer from radiation, evaporation through the open top, conduction through the tank walls, and convection on all surfaces. I can do the conduction and radiation calculations, but I am unsure about how to do the calculations for evaporation and convection. Any help with this would be greatly appreciated!
