two identical rectangular rods of metal are welded rods of metal are welded end to end to end as shown in Fig. 23-27a, and 10 J of heat flows through the rods in 2.0 min. How long would it take for 30 J to flow through the rods if they are welded as shown in Fig. 23-27b?

So, time t will be,
t = W/H
To find the rate of heat transfer Ho for the rectangular rod which are connected in series (configuration (a)), substitute 10 J for W and 2 min for t in the equation t = W/H,
Ho = W/t
