(9 pоints) Wаter аt 1 аtm is heated in a mechanically pоlished stainless-steel pan, with its surface is electrically heated tо Ts = 110°C. The pan’s diameter is 20 cm. What is the power required to boil the water? Use the following properties for your calculations: Tsat = 100°C, liquid phase’s density = 957.9 kg/m3, vapor phase’s density = 0.5956 kg/m3, liquid phase’s specific heat = 4217 J/(kg×K), liquid phase’s dynamic viscosity = 279×10-6 Pa×s, liquid phase’s Prandtl number = 1.76, hfg = 2,257,000 J/kg, Surface tension = 0.0589 N/m.
