for which cycle traversed clockwise is W greater and Q greater? Please explain as thoroughly as possible. THERMODYNAMIC in6 Figure 18-26 shows e three different arrange- Figurrent ar and ments of materials 1,2, and1/2/3 3 to form a wall The ther- mal conductivities are k > >k.The left side of the arrange 1 2 3 1 3 2 3 k(a) Figure 18-26 Question 6. wall is 20 Co higher than the right side. Rank the arrangements according to (a) t ate) rate of energy conduction through the wall andSteady rature difference across material 1, greatest first. Figure 18-27 shows closed cvcles on ts according to (a) the (ste ts accordn h the wall and (b) the temi- wall and (b) the and (b) the tenExplanation / Answer
Rate of heat transfer Q/t = k A(T2-T1)/ t
k thermal conductivity value, A area, t thickness , T2-T1 id temperature difference
the rate of energy conduction is proportional to k,A, dT, inversly proportional to thickness, here thickness of all materials are same so
as given in the diagram the rate of energy conduction through the wall is (a)>(b)>(c)
because k1>k2>k3
b)
the temperature difference across the material 1 is all are same a=b=c
