This cartoon is can be yours truly as I often get up in the night only to nap on the couch. More importantly, Mr Tinkerson made a coffee only to let it cool on a table, which is perfect for a convection problem. Let's assume the cup is a typical cup with a top rim diameter of 75.0 mm. Judging by the steam above the cup-o-coffee it must be at a typical 175 degF. If the room temperature is 19.0 degC, what is the rate (W) of heat transfer via convection from the top of the coffee into the room? Assume h= 5.2 J/s*m^2* Cdeg
