The beaker for 3 minutes heated up above a candle across three trials Trial To water(C) T' water after (C) 1 22 32 2 22 31 3 22 32 . Calculate the heat flux (q') and heat rate (q) for each temperature using Stephan-Boltzmann's equation. Consider the total area of the beaker (walls and only one base). Consider the emissivity of the flame equal to 0.9 and the temperature of the candle approximately 400 C (3 points) Calculate the heat flux (q) and heat rate (q) for each temperature using Fourier's Law. Assume a linear temperature gradient. Consider the thickness of the beaker equal to 1 mm. (3 points) Report the heat rate results as average with the deviation standard in a table for the different temperatures and different heat transfer processes. Include a title for the table and the units. Compare the results and discuss which mode of heat transfer dominated the process. (2 points) Define what other processes aside from radiation and conduction could also contribute to the process of heat transfer in this specific example (2 points)
