Heat transand P 5.8 The heat transfer coefficient for air flowing over a sphere is to be determined by observing the temperature-time history of a sphere fabricated from pure copper. The sphere, which is 12.7 mm in diameter, is at 66°C before it is inserted into an airstream having a temperature of 27°C. A thermocouple on the outer surface of the sphere indicates 55°C 69 s after the sphere is inserted into the airstream. Assume and then justify that the sphere behaves as a spacewise isothermal object and calculate the heat transfer coefficient. T 2706

As part of your work-study program at HTU, you successfully got a student job at your local ‘BEST-BURGER-IN-TOWN’ to help pay your own tuition and expenses. Since cylindrical frozen burger patties are cooked when placed on a hot stainless-steel cooking top, you like to think of the case as a conduction problem:a. Write down the appropriate general heat conduction equation that describes the cooking of those beef patties.b. Clearly state all assumptions.c. After cancelling the proper terms, write down the final energy equation for the patties.Do not solve for temperature distribution or heat transfer.
