Saturated ethylene glycol at 1 atm is heated by a horizontal chromium-plated surface which has a diameter of 200 mm and is maintained at 480 K. Estimate the heating power requirement and the rate of evaporation. What fraction is the power requirement of the maximum power associated with the critical heat flux? At 470 K, properties of the saturated liquid are μ = 0.38 x 10^-3 N ∙ s/m², c p = 3280 J/kg ∙ K. and Pr = 8.7. The saturated vapor density is p = 1.66 kg/m³. Assume nucleate boiling constants of C_s,f = 0.01 and n = 1.0.
