Homework Statement
An 16m by 9.0m house is built on a concrete slab 20cm thick. What is the heat-loss rate through the floor if the interior is at 29°C while the ground is at 19°C?
Given:
Area = 16*9 = 144m^2
DeltaX = 20cm = 0.2m
DeltaT = 29-19 = 10°C
k = not given
H = ?
Homework Equations
Equation (i believe): H = (-k*A*DeltaT)/DeltaX
The Attempt at a Solution
I calculated the heat loss with the above given details but apparently the answer does not depend on the variable k (thermal conductivity).
Anyone got any ideas?
