Q2) A constant heat flux (a -50 W/m2) is applied to a 1-D plane wall (k - 0.4 W/m K) on one side. The other side is subjected to convective boundary condition (h- 10 W/m? .K.Tm-25°C). A volumetric heat (q = 300 W/m*) is generated in the plane wall. If the plane wall has a thickness of L = 100 mm, a) Calculate surface temperatures T(x 0) and T(xL). b) Determine the location of the maximum temperature in the slab....

Question: 1 What is the maximum heat flux (Critical Heat Flux) for HFE-7000 according to Kutateladze's maximum heat flux correlation, in W/m2? Use the Zuber Constant (pi/24) for C. Question: 2 What was the minimum heat flux data point (Leiden frost Point) at the bottom of the film-boiling region of Nukiyama's experiment, in W/m2? Can you expect a similar value in our experiment? Question: 3 Estimate the excess temperature at CHF for HFE-7000 using the Rohsenow equation and the results...

PROJECT #1 (2.5 Marks): The heat that is conducted through a body must frequently be removed by other heat transter processes. For example, the heat generated in an electronic device must be dissipated to the surroundings through convection by means of fins. Consider the one-dimensional aluminum fin (thickness t 3.0 mm, width Z 20 cm, length L) shown in Figure 1, that is exposed to a surrounding fluid at a temperature 1. The conductivity of the aluminum...

Problem #1 Ski Jacket Estimated Rate of Heat Loss A typical ski jacket is manufactured using thin layers of fabric separated by regions of trapped air. Consider a jacket that contains 5 uniform layers of fabric where each layer is separated by a 1.5 mm thick air space. The thermal conductivity of the synthetic fabric used has been estimated to be 0.13 W/m C. The thickness of fabric is 0.1 mm The total surface area of jacket has been estimated...

2) Understanding Quenching with SOV Quenching is a common engineering practice by which a hot object (usually metal) is submerged into a fluid and cooled to the desircd tempcrature. Consider the quenching of a square metal sheet with side length, W, much greater than the sheet thickness, L, such that the heat transfer can be considered one dimensional in the thickness direction. Here the metal sheet is initially at a uniform temperature, T1, when it is submerged into a fluid...
