The bottom of a copper pan, 300 mm in diameter is maintained at 120° C by an electric
heater. Calculate the power required to boil water in this pan. What is the evaporation rate?
Estimate critical heat flux. Take properties of saturated water at 100° C are:
hig = 2257 kJ/kg, p = 957.9 kg/m, p, = 0.595 kg/m' , k; = 0.668 W/m.K, u = 279 x 10 kg/ms.
Pr = 1.76, C, = 4.217 kl/kg.K, a =
%3!
G = 58.9x 10° N/m.
