Answer:
heat flow is 106.1 W
Explanation:
given data
length = 0.875 m
dimensions x = 0.0515 m
dimensions y = 0.0855 m
temperature = 42.9°C and 97.7°C
thermal conductivity K = 385 W/(m⋅K)
to find out
heat flows
solution
we will apply here formula for heat flow that is
heat flow = K × Δt × A / L ..........................1
so here Δt = 97.7°C - 42.9°C = 54.8°C
and area A = xy = 0.0515 × 0.0855 = 4.40 × m²
so put all value in equation 1 we get heat flow
heat flow = K × Δt × A / L
heat flow = 385 × 54.8 × 4.40 × / 0.875
heat flow = 106.1
so here heat flow is 106.1 W
