Homework Statement
The amount of heat per second conducted from the blood capillaries beneath the skin to the
surface is 240 J. The energy is transferred a distance of 2.0×10−3mthrough a body whose surface area is 1.6 m2. Assuming that the thermal conductivity is that of body fat 0.2 J /(s ⋅m⋅o C) , determine the temperature difference between the capillaries and the surface of the skin.
So k = .2
A = 1.6 m^2
L = 2.0 x 10^-3m
I'm not sure what the 240 J goes as? Is that Q?
Homework Equations
This is basically where I'm stuck... I'm not sure what equation to use.
I was thinking possibly Q = k * A * change in T * time all divided by L ... but there's no mention of time?
