Homework Statement
Suppose that you own a poorly insulated small house, with outside walls l = 0.25m thick, total outer wall plus roof
surface area 210m^2 (about 1992 ft^2) and your walls have a thermal conductivity of 1.3 W/m·K (limestone). Calculate
how much power your air conditioner will require to keep your house at 293K when the outside temperature is 308K.
Homework Equations
maybe dQ/dt = ak(dT/dx)
The Attempt at a Solution
i think
(1.3)(210)(15/.25) = 16380 W
but what do you think? have i made errors?
