The filament in a light bulb has a diameter of 0.02 mm and an emissivity of 1.0. The temperature of the filament is 3×1000°C. What should be the length of the filament in meters so it will radiate 60 W of power? The Stefan-Boltzmann constant is 5.670 × 10-8 W/m2 · K4. Please give your answer with 3 decimal places.
You are insulating a metal pipe carrying a hot fluid. The outside Diameter of the pipe is 3.5 cm, and the pipe has a length of 7.7 meters. Due to the fluid inside the pipe, the outside surface of the metal fluid pipe is kept at a constant temperature of 85.0°C. The metal pipe is inserted inside of a thin-wall circular tube, which has an inside diameter of 11.2 cm (ignore the resistance of the thin-wall circular tube). The space between the outside of the hot metal pipe and the inside of the thin-wall circular tube is filled with foam insulation, k = 0.036 W/m-K. The outside of the thin-walled circular tube is kept at a constant temperature of 28.0°C. Due to a manufacturing error, the metal pipe was not centered inside the thin-wall tube when the foam insulation was added, but was instead installed with an eccentricity of 2.0 cm (i.e. the center of the metal pipe is 2.0 cm distance from the center of the thin-walled circular tube). Calculate the increase in the heat transfer rate due to…

Question D1 30 g sweet potato strips originally placed in room temperature (25°C) was deep fried by an electric deep fryer containing 180°C peanut oil. Given that specific heat capacity of sweet potato = 3.50 J/g °C, specific heat capacity of peanut oil = 1.97 J/g °C, standard voltage in Hong Kong = 220V. (a) How much energy is required to heat up 30 g sweet potato strips to 180°C? (b) Given that the resistance of the deep fryer is 22.0 2, what is the power rating of the deep fryer? (c) Assume 10% of the energy delivered by the deep fryer is lost to the surroundings, how long does it take (i.e. time required) to heat up 30 g sweet potato strips to 180°C? (d) If it takes 4 more minutes to fry the sweet potato strips into crispy golden brown at 180°C, how much energy is delivered by the deep fryer throughout the whole cooking process.
