Consider a 1000-W iron whose base plate is made of 0.5-cm-thick aluminum alloy 2024-T6 (r = 2770 kg/m3 and cp = 875 J/kg·°C). The base plate has a surface area of 0.03 m2. Initially, the iron is in thermal equilibrium with the ambient air at 22°C. Assuming 90 percent of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°C.
An electric immersion heater has a power rating of 1800 W. If the heater is placed in a 1.3 kg of water at 30 °C, how many minutes will it take to bring the water to a boiling temperature? (Assume that there is no heat loss except to the water itself. water=4186 J/kg.°C)
You have a pure copper electrical wire with a diameter of 0.205cm and an electrical resistance of 0.0053Ω/m. The wire is exposed to uniform convection of T_inf = 22.0°C, h_inf = 15.0 W/(m2-K).
