Answer:
entire wall temperature difference = 29.29 K
Explanation:
given data
temperature difference steel ΔT = 17.79 K
steel L = 1.471 cm
lead L = 2.416 cm
to find out
temperature difference across wall
solution
we know that here heat transfer by steel and lead are same
and
heat transfer = k×A×ΔT / L ................1
so
H( lead) = H (steel)
k×A×ΔT / L = k×A×ΔT / L .................2
here we know
k for steel = 14.4 W/mK
k for lead = 36.6 W/mK
so put here all value in equation 2
k×ΔT / L = k×ΔT / L
36.6×ΔT / 2.416 = 14.4×17.79 / 1.471
ΔT = 11.50 K
so
entire wall temperature difference = 11.50 + 17.79
entire wall temperature difference = 29.29 K
