Water is boiled at the rate of 25kg/h in a polished copper pan, 280mm in diameter at atmospheric pressure. Assuming nucleate boiling conditions calculate the temperature of the bottom surface of the pan.
“..for polished copper and water combination”
“…heat of vapourization of water at 1 atm.”
… "total heat supplied to boil 25 kg/h of water”
Thus, surface temp,
