A plate (74 + 0.3) m long and (74 + 0.1) m wide, with a thickness of (74 + 12) mm is made from stainless steel ( k= 16 W/mK). The temperature at the bottom surface of the plate is 100 °? maintained by an electrical heater supplied by 200 V and 0.25 A. In a steady-state condition, assuming that the plate is perfectly insulated on all sides except top surface, find temperature at the top surface of the plate.
Presents the diagram of the problem, necessary formulas, clearance and numerical solution: A poorly designed electronic device has two screws attached to different parts of the device that almost touch each other inside. steel bolts and brass are at different electrical potentials and if they touch, a short circuit will develop will damage the device. The initial separation between the ends of the screws is 5 μm to 27 ◦C. At what temperature will the screws touch? Assume that the distance between the walls of the device is not affected by temperature change and the coefficient coefficients of linear expansion αlaton = 19x10−6 ◦C −1 and αsteel = 11x10−6 ◦C −1
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.
A 300 g aluminum pot containing 0.50 L of water is placed on the 1 kg iron hot plate on an electric stove. The heating element of the hot plate is rated at 1.5 kW. If the hot plate, the pot, and the water are all at 20 oC when the heating element is switched on, how long will it take until the water begins to boil? Neglect heat losses to the surroundings.
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…
