A wall (assumed to be 1-dimensional) has a thickness of 2L-8em and experiences uniform thermal energy generation of 9 1000 ms. The wall is cooled convectively at x = ±4 cm by a fluid at temperature T,-30°C. The steady-state temperature distribution through the wall is T(x) = a(L2-x*) + b, where a = 15°C/mz and b = 40°C. Determine 4. a. b, The thermal conductivity of the wall, k The convection coefficient, h
A plane wall of thickness 2L= 30 mm and thermal conductivity k= 3 W/m·K experiences uniform volumetric heat generation at a rate q˙, while convection heat transfer occurs at both of its surfaces (x=-L, +L), each of which is exposed to a fluid of temperature ∞T∞= 20°C. Under steady-state conditions, the temperature distribution in the wall is of the form T(x)=a+bx+cx2 where a= 82.0°C, b= -210°C/m, c= -2 × 104°C/m2, and x is in meters. The origin of the x-coordinate...
Problem 3. A plane wall of thickness 2L = 40 mm and thermal conductivity k = 5 W/m.K experiences uniform volumetric heat generation at a rate ġ, while convection heat transfer occurs at both of its surfaces (x = -1, + L), each of which is exposed to a fluid of temperature Too = 20 °C. Under steady-state conditions, the temperature distribution in the wall is of the form T(x) = a + bx + cx? where a = 82.0°C,...
