Explanation:

full question

A 10m×15m house is built on a 14 cm -thick concrete slab. What is the heat-loss rate through the slab if the ground temperature is 7 ∘C while the interior of the house is 23 ∘C?

solution

Given: A (10 m x 15 m) = 150 m²

L = 14 cm = 0.14 m and

ΔT = 16 ∘C

Rate of heat loss(Q/t) = KA . ΔT      (Here, K = 0.8 w/m∘C)

                                          L

Q/t = 0.8 × 150 × 16

                0.14

   = 13714.286 W
