Heat is uniformly generated at the rate of 2x 10W/m* in a wall of thermal conductivity 25 W/m-K and thickness 60 mm. The wall is exposed to convection on both sides, with different heat transfer coefficients and temperatures as shown. There are straight rectangular fins on the right-hand side of the wall, with dimensions as shown (L =20 mm) and thermal conductivity of 250 W/m-K. What is the maximum temperature that will occur in the wall? L tt-2 mm k=25...
03 Multipart Questions Conferences It is proposed to air-cool the cylinders of a combustion chamber by joining an aluminum casing with annular fins ( k= WileyPLUS Sup- port 215 W/m-K) to the cylinder wall k = Collaborations 50 W/m K). The air is at 320 K and the corresponding convection coefficient is 100 W/m2-K. Although heating at the inner surface is periodic, it is reasonable to assume steady-state conditions with a time-averaged heat flux of Chat Browse NBC 1 x...
Consider a rectangular fin (k = 180 W/m-K) of length L =10 mm, thickness i =1 mm, and width w» t. The base temperature of the finis Ty = 150°C, and the finis exposed to a fluid of temperature T, =25°C. Assuming a uniform convection coefficient of h = 110 W/m2.K over the entire fin surface, determine the fin heat transfer rate per unit width 4; efficiency ng: effectiveness es, thermal resistance per unit width and the tip temperature T...
Consider the manufacture of photovoltaic silicon where a thin sheet of silicon is pulled from the pool of molten material very slowly and is subjected to an ambient temperature of T 627°C within the growth chamber. The silicon sheet is Wsi =85 mm wide and tsi =150um thick. A convection coefficient of h 7.5 W/m2.K is associated with the exposed surfaces of the silicon sheet when it is inside the growth chamber. Calculate the maximum allowable velocity of the silicon...
finite element method 2. Aluminum fins with rectangular profiles (5 mm wide and 1 mm thick) are used to remove heat from a surface whose temperature is 150°C. The temperature of ambient air is 20°C. The thermal conductivity of aluminium is 168 W/m.K. The natural convective coefficient associated with the surrounding air is 35 W/m2.K. The fins are 150 mm long and the heat loss from the tip of the fin may be neglected. (a) Determine the temperature distribution along...
I. Design of Fins (35 pt). A stripping process produces a hot fluid (80°C) that flows inside copper pipe of 20 cm diameter (the thickness of the pipe wall is negligible). Outside the pipe, there is air flow at ambient temperature (20 °C). In order to recirculate the fluid produced, it is necessary to cool it down. This can be achieved by installing ten circular fins per meter of pipe (see figure below). These fins have a thickness of 0.1...
It's a heat transfer question. Please do not copy from others, thank you. The chip is square with dimensions 15mm by 15mm and 5mm thickness with constant temperature Tc = 87 degrees C at the bottom of the chip. At the top surface, 20 pin fins with convective ends are attached to the chip. Above the chip, we have the 20 fins plus we also have the exposed board area, which is total area of the chip minus the base...
To maximize production and minimize pumping costs, crude oil is heated to reduce its viscosity during transportation from a production field. (1) Consider a pipe-in-pipe configuration consisting of concentric steel tubes with an intervening insulating material. The inner tube is used to transport warm crude oil through cold ocean water. The inner steel pipe ks 45 W/m-K) has an inside diameter of Di,1 150 mm and wall thickness t = 20 mm while the outer steel pipe has an inside...
Question 11 (15 points) The wall of a liquid-to-gas heat exchanger has a surface area on the liquid side of 1.8 m2 (0.6 m * 3.0 m) with a heat transfer coefficient of 255 W/m2 K. On the other side of the heat exchanger wall a gas flows, and the wall has 96 thin rectangular steel fins 0.5 cm thick and 1.25 cm high (k = 3 W/m K) as shown in the figure below. The fins are 3 m...
