Chapter 1, Problem 1.2P

The heat flux that is applied to the left face of a planewall is q = 20 W/m 2 . The wall is of thickness L = 10 mm and of thermal conductivity k = 12 W/m K . If the surface temperatures of the wall are measured to be50°C on the tell side and 30°C on the right side, do steady-state conditions exist?

1. Temperatures are measured at the left-hand face and at a point 4 cm from the left-hand face of the planar wall shown in the figure below. These temperatures are T₁ = 45.3 °C and T* = 21.2 °C. The heat flow through the planar wall is steady and one dimensional. What is the value of T2 at the right-hand surface of the wall? TI T* 4 cm 10 cm T2
Consider a plate whose thickness is 2L=20 cm and thermal conductivity is 44 W/mK. Heat generation inside the plate (5x105 W/m³) is uniform. The surface of the plate is maintained at Ts=10°C. Find the temperature at the center of plate. T Ts -L L X O a. 45 °C ОБ.75 °С О с. 67 оС O d. 90 °C O e. 85 °C
The heat flux that is applied to the left face of a plane wall is q conductivity k = 12 W/m-K. = 50 W/m². The wall is of thickness L = 12 mm and of thermal If the surface temperatures of the wall are measured to be 50°C on the left side and 30°C on the right side, then steady-state conditions have been reached. then steady-state conditions have not been reached.
