Water is to be boiled at atmospheric pressure in a polished copper pan by means of an electric heater. The diameter of the pan is 0.48 m and is kept at 108 deg c. What is the power required to boil the water? Tsat = 100°C; Properties of water at 100°C: Density, pl= 961 kg/m3; Kinematic viscosity., v = 0.293x10-6 m2/s; Prandti Number, Pr = 1.740; Specific heat, Cpl = 4216 J/kg.K; Dynamic viscosity, u = p x v = 961 x 0.293 x 10-6 = 281.57 x10-6 Ns/m2; hfg = 2256.9 kj/kg; pv = 0.597 kg/m3; 0 = 0.0588 N/m: Csf=0.013; n=1: Select one: O a. 11633.5098 O b. 13259.1393 O c. 16641.2421 O d.9493.7946
