Consider a square pan with a polishedcopper surface that is filled with hot water. The bottom of the pan, which is 0.5 m long, is exposed to air at pressure of 1 atm and a temperature of 306.15 K (T[infinity]) with a velocity of 10 m/s (u[infinity]). The lateral surfaces of the electrical heater are thermallyinsulated. If the temperature of the pan (Ts) needs to be maintained at 393.15 K, what is the electrical heating power required to boil water in this pan with these conditions (in W)? Hint: Rohsenow Correlation is valid, and for the polished copper, you can use Cs, fas 0.0128 and nas 1. You can also assume the heater has a uniform temperature.
