he thermal conductivity of a specific material is highly dependent on a number of factors. These include the temperature gradient, the properties of the material, and the path length that the heat follows. My question is how to add thermal conductivity? for example SS316 material has thermal conductivity=15W/mk if Gyroid shape is created with SS316 then what will be the total thermal conductivity?

5.10 Experiments have been performed on the temperature distribution in a homogeneous long cylinder (0.1 m diameter, thermal conductivity of 0.2 W/m K) with uniform internal heat generation. By dimensional analysis, determine the relation between the steady-state temperature at the center of the cylinder , the diameter, the thermal conductivity, and the rate of heat generation. Take the temperature at the surface as your datum. What is the equation for the center temperature if the difference between center and surface temperature is when the heat generation is ?
1.63 Liquid oxygen (LOX) for the space shuttle is stored at 90 K prior to launch in a spherical container 4 m in diameter. To reduce the loss of oxygen, the sphere is insulated with superinsulation developed at the U.S. National Institute of Standards and Technology's Cryogenic Division; the superinsulation has an effective thermal conductivity of 0.00012 W/m K. If the outside temperature is on the average and the LOX has a heat of vaporization of 213 J/g, calculate the thickness of insulation required to keep the LOX evaporation rate below 200 g/h.
1.77 Explain each in your own words. (a) What is the mode of heat transfer through a large steel plate that has its surfaces at specified temperatures? (b) What are the modes when the temperature on one surface of the steel plate is not specified, but the surface is exposed to a fluid at a specified temperature?
After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). How many years would it take to melt the iceberg solely by heat from the sun if the ice absorbs a mean of 98 J/m2 -s, 12.5 hrs per day? Note: the exposed area for heating is 250 km x 50 km and the density is 920 kg/m3 . This is my solution.

Then the four sides are instantly heated up to 25 degrees Celsius, 50 degrees Celsius, 30 degrees Celsius, and 0 degrees Celsius. a. Find how long it takes for the temperature profile of this square to become steady if the material is copper. What is the final temperature at the center of the square? b. Find how long it takes for the temperature profile of this square to become steady if the material is air. What is the final temperature at the center of the square? c.

You are designing a small heatsink to cool a high-powered IC on a control unit PCB. The IC puts out 40,000 W/m2 and has a size of 40mm x 20mm. A fan blows 40 degrees C air across the IC at a speed of 4 m/s. The IC is well insulated on its back face. If the convection coefficient is 62 W/m2K, what is the surface temperature of the IC?
You are designing an enclosure which houses a PCB. Mounted outside the enclosure on its top is a set of aluminum fins, as seen in the sketch below. The enclosure (and fins) are 150mm deep long. There is no forced airflow. Neglect the thickness of the enclosure walls. Neglect heat transfer out of the sides and bottom of the enclosure. If the PCB produces 4000 W/m2: a) Most industrial-grade ICs have a maximum temperature of 85oC. If you must keep your PCB below this what is the maximum thermal resistance from the PCB to the air surrounding the fins? Assume the air around the fins stays at room temperature. b) If the top of the enclosure (and bottom of the fin base) runs at 50°?, what is the effective thermal conductivity above the PCB? Hint: Because the air inside the enclosure is trapped and heats up, any air properties NOT given below are calculated at the average air temperature (T1+T2)/2. c) What is the temperature at the base of the fins? d) What is the efficiency of the fins? e)…
please make it 1 paragraph in the abstract below, with the journal name Optimizing the thermal management system of PCM fin-structured Li-ion batteries under mechanical vibration conditions: A comparative study because I have difficulty combining can you please ask for help to try the writing below, so that the results are maximized The thermal management of battery systems using Phase Change Materials (PCM) commonly faces challenges due to the low thermal conductivity of PCM. This study introduces innovative fin structures comprising longitudinal fins and cylindrical rings to enhance heat transfer. Comparative experiments are initially designed to assess the thermal performance of various Battery Thermal Management Systems (BTMS). Results indicate that the PCM-Fin system outperforms both the pure battery system and the PCM system. Numerical simulations, validated with experimental data, uncover the underlying mechanisms. The fin structures not only increase the heat transfer area…

Yes it is hard but please I need help with this A horizontal 8 cm OD pipe carries steam at 150°C through a room at 17°C. The pipe is covered by a1.5 cm layer of magnesia insulation. What is the heat loss per meter of the pipe?• For this configuration if a horizontal cylinder, NuD = f (RaD, Pr) can be found using equation 8.28• I assume since material and thickness of the pipe inside the insulation are not given, nor is any flow data onthe steam that these resistances are negligible.• The temperature of the outer insulation is not initially known. I guessed it and used a circuit diagram with tworesistances to find Q, then used one circuit to find the wall temp, and iterated. I updated my material propertieswith my wall temperature changes. It converged quickly.• My answer is 5-10% higher than the books. Not sure why.
