7. A pan made of stainless steel contains water at atmospheric pressure. The pan diameter is 25 cm and its surface is mechanically polished. The pan is now heated while its surface is maintained at 116 C. Find the surface heat flux, the boil off (evaporation) rate, and the peak heat flux. [Ans.: 4" = 5.6E5 W/m², m= 44 kg/h, and gcuE = 1.27 MW/m. Note that the operating heat flux is less than half of the peak heat flux hence, a safety factor of 1.27E6/0.56E6 = 2.26].
