Question 43
MTNAT2 marksNeeds review
As shown in schematic below, an alloy is cast as a rectangular slab between two thick mould walls that differ in their thermal conductivities. Shrinkage defects are found at a distance L1 from Mould-1 with thermal conductivity
and distance L2 from Mould-2 with thermal conductivity
. If the ratio L1:L2 = 3:2, and assuming 1-D heat transfer, the ratio
is ______ (to two decimal places)
