Water is to be boiled at atmospheric pressure in a mechanically
polished stainless-steel pan (Csf=0.013 and n = 1) placed on top of
a heating unit. The inner surface of the bottom of the pan is
maintained at 108°C. If the diameter of the bottom of the pan is 30
cm, determine the rate of heat transfer to the water. The
properties of water at the saturation temperature of 100°C are: σ =
0.0589 N/m, ρl = 957.9 kg/m3, hfg = 2257.0 × 103 J/kg, ρv = 0.6
kg/m3, µl = 282 × 10-6 kg m/s, Prl = 1.75, Cpl = 4217 J/kg
°C.
