b) A steel pipe of 100mm bore and 7mm thickness transports steam at 260 °C. The pipe is insulated with 40mm of a molded high temperature diatomaceous earth covering. This covering is in turn insulated with 60mm of asbestos. If the atmospheric temperature is 25 °C, calculate the rate at which heat is lost by the steam per meter length of the pipe.

Build a spreadsheet to do the step by step method for estimating the temperature of unprotected steel work exposed to the ASTM E119 Standard Fire. Assume a convective heat transfer coefficient of 25 W/m2K and an emissivity of 0.5. Assume the specific heat to remain constant at 600 J/kgK. Use a time step of 30 seconds and an ambient temperature of 20°C. Provide an Excel plot showing the curves of the fire and a steel member through a time of 60 minutes with F/V ratios of: a)25 m-1 b)100 m-1 c)200 m-1 d)300 m-1 Note your plot should contain 5 curves. One for the fire and one for each of the F/V values. Also on the spreadsheet, highlight in green, the cells identifying the temperature of the unprotected steel member with an F/V of 200m-1 at the following times: a)3 minutes b)10 minutes c)20 minutes d)50 minutes
A superalloy gas turbine component was originally designed to operate at temperatures up to 760°C and exhibited a stress rupture life of 900 h under this operating condition. An updated design calls for a thermal barrier coating to be added to the same component to allow engine operation under the same conditions, but with an increase in reliability. If an increase in rupture life to 1800 h is desired, what temperature differential between the inside and outside of the component must be achieved by the addition of the TBC?
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.
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)…
Two inches of urethane foam will reduce heat loss close to 1000% when applied to a 2-inch diameter uninsulated steel pipe. Assume the pipe wall thickness is 0.25-inches, the pipe interior convective heat loss (hi) is 500 BTU/hr-ft2-oF, and the pipe outside convective heat loss ho 20 BTU/hr-ft2-oF, k steel is 25 BTU/hr-ft-oF, and k insulaton is 0.023 BTU/hr-ft-oF. (hint - calculate heat loss with and without insulation.

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…
