(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The absolute value of the heat flow rate through a slab of area 0.83 m2 is 240 W. The

thickness of the slab is 1.4 cm and its thermal conductivity is 0.6 W/(m·K). If the hot surface of the slab is at 40°C find the temperature of the cold surface.

2. Relevant equations

H = -kA([tex]\Delta[/tex]T/[tex]\Delta[/tex]x)

H = Q/t?

3. The attempt at a solution

A = 0.83 m^2; [tex]\Delta[/tex]x = 1.4; k = 0.6 W/(m·K); Thot = 40°C;

Missing H?
