1. Water is to be boiled at atmospheric pressure in a mechanically polished steel pan of 30 cm diameter placed on top of electric heater that transfers 75% of its rated power to the pan. The thickness of the pan is 5 mm. (a) If water is to be boiled at a rate of 1 gram/s, find the power rating of the heater necessary for this task. (b) What is the temperature of the pan surface in contact with water? (c) What is the temperature of the bottom of the pan in contact with electric heater? (d) Find the peak heat flux and maximum heat flux for the given arrangement. The following data is available at the average temperature. 957.9 kg/m3 0.6 kg/m3 rhol rhov sigma Cpl Cpv mul kl ks hfg Tsat 0.0589 N/m 4217 J/kg/K 1890 J/kg/K 2.82E-04 kg/m/s 0.677 W/m/K 14.9 W/m/K 2.257E+06 J/kg 373 K
