1. Water at atmospheric pressure is to be boiled in polished copper pan. The diameter of the pan is 300 mm and is kept at 111°C. Calculate the following : (1) Power of the burner to maintain boiling: (i) Rate of evaporation in kg/ħ. Take the properties of water at 100°C as follows: P, = 958 kg/m²; p, = 0.597 kg/m²; µ,= 278 × 10ʻ kg/ms; c= 4216 JkgK; h = 2257 kJ/kg ; Pr =1.723, ở = 58.9 × 10 N/m (Ans. (1) 13.664 kW, (i1) 21.8 kg/h]
