Two identical long, thin, solid cylinders are used to conduct heat from a reservoir attemperature Thot to a reservoir at temperature Tcold. Originally the cylinders areconnected in series as shown in Fig. 23-24, and the rate of heat transfer is H0. Ifthe cylinders are connected in parallel instead as shown in Fig. 23-24b, then what wouldbe the rate of heat transfer?(A) 16H0(B) 4H0© 2H0(D)H0/2(E) the answer depends on the thermal conductivity, K, of the cylinders.
