The coefficients of thermal conductivity...

The coefficients of thermal conductivity of copper, mercury and glass are respectively `K_c`, `K_m` and `K_g` such that `K_c > K_m > K_g`. If the same quantity of heat is to flow per second per unit area of each and corresponding temperature gradients are `X_c`, `X_m`and `X_g`, then

A

`X_c = X_m = X_g`

B

`X_c > X_m > X_g`

C

`X_c < X_m < X_g`

D

`X_m < X_c < X_g`

One end of a metal rod of length 1.0 m and area of cross section 100cm^2 is maintained at 100° C. If the other end of the rod is maintained at 0°C, the quantity of heat transmitted through the rod per minute is (Coefficient of thermal conductivity of material of rod =100 W/m-K)

An iron bar (L_(1) = 0.1 m , A_(1) = 0.02 m^(2), K_(1) = 79 W m^(-1) K^(-1)) and a brass bar (L_(2) = 0.1 m, A_(2) = 0.02 m^(2) , K_(2) = 109 W m^(-1) K^(-1)) are soldered end to end as shown in Fig. 11.16. The free ends of the iron bar and brass bar are maintained at 373 K and 273 K respectively. Obtain expressions for and hence compute (1) the temperature of the function of the two bars, (11) the equivalent thermal conductivity of the compound bar, and (111) the heat current through the compound bar.

Seven rods A, B, C, D, E, F and G are joined as shown in figure. All the rods have equal cross-sectional area A and length l. The thermal conductivities of the rods are K_(A)=K_(C)=K_(0) , K_(B)=K_(D)=2K_(0) , K_(E)=3K_(0) , K_(F)=4K_(0) and K_(G)=5K_(0) . The rod E is kept at a constant temperature T_(1) and the rod G is kept at a constant temperature T_(2) (T_(2)gtT_(1)) . (a) Show that the rod F has a uniform temperature T=(T_(1)+2T_(2))//3 . (b) Find the rate of heat flowing from the source which maintains the temperature T_(2) .
