An infinitely long pin fin, attached to an isothermal hot surface, transfers heat at a steady rate of Q to the ambient air. If the thermal conductivity of the fin material is doubled, while keeping everything else constant, the rate of steady-rate heat transfer from the fin becomes Q. The ratio is (a) 2 (b) 1 (c) J2 (d) 2 1/2

Q.3) The two sides of a large plan wall are maintained at constant temperatures of T₁ = 120°C and T₂ = 50°C, respectively. If you know that the wall thickness L = 0.2 m, thermal conductivity k = 1.2 W/m.K, and surface area A = 15 m². Determine (a) the variation of temperature within the wall and the value of temperature at x = 0.1 m and (b) the rate of heat conduction through the wall under steady conditions. (10 Pts)
A sphere ( k=204 W/m K) with inner diameter 4 cm and outer diameter of 8 cm . The inside temperature is 100C and the outer temperature 50 C . Calculate the rate of heat transfer
A cylindrical pipe is made up of two materials. The inner material A, which has thermal conductivity of ka, has inner radius ra and outer radius re. On the other hand, the outer material B, which has thermal conductivity of kb, has inner radius re and outer radius rb. Contact resistance between the two materials is known to be hc. The temperature at the inner radius of material A (at ra) is Ta, while the temperature at the outer radius of material B (at ri) is T3. Find an expression for the temperature at the inner radius of material B (at r.) in terms of the given variables.
A large plate of 0.5 m thickness and constant thermal conductivity of k=60 W/m⋅K in which heat is generated uniformly at a rate of 2 kW/cm3.

Heat Transfer A wall of an oven with a wire in it. Across the wire a voltage of 50 Volts and a current of 2 Amps is applied, and 80% of the electrical power is converted to thermal energy. The oven is a convection oven and has air flowing through it at 240 C and h = 10 W/m^2 K. The wall of the oven is 0.1 m thick and 1.5 m tall and 1.5 m wide and is made of steel (k = 15 W/m K). Find the surface energy balance on the inner wall of the oven and determine the temperature of the ineer wall at steady state. Then do an energy balance on the outer wall, assume that the oven is free standing and has an emissivity, e = 0.6, and the surrounding temperature is 25 C. The air in the surrounding has a convective heat transfer coefficient of 25 W/m^2 K. Just set up the balance equation that would enable to solve, no need to actually solve.
