Three bars of equal lenghts and equal area of cross-section are connected in series. Their thermal conductivities are in the ratio of `2:4:3`. If the open ends of the first and the last bars are at temperature `200^(@)C` and `180^(@)C` respectivity in the steady state, calculate the temperature of both the junctions.

Three bars of equal lengths x and equal area of cross-section A are connected in series. Their thermal conductivities are in the ratio 2:4:3. If the open ends of the first and the last bars are at temperatures 200^@C and 18^@C , respectively in the steady state, calculate the temperatures of both the junctions.

Three bars of equal lengths and equal area of cross-section are connected in series fig. their thermal conducitives are in the ratio 2:3:4 . If at the steady state the open ends of the first and the last bars are at temperature 200^(@)C and 20^(@)C respectively, find the temperature of both the junctions. .

Three cylindrical rods A, B and C of equal lengths and equal diameters are joined in series as shown if Fig. Their thermal conductivities are 2K, K and 0.5K, respectively. In steady state, if the free ends of rods A and C are at 100^@C and 0^@C , respectively, calculate the temperature at the two junction points. Assume negligible loss by radiaiotn through the curved surface. What will be the equivalent thermal conductivity?

Two ends of a conducting rod of varying cross-section are maintained at 200^(@)C and 0^(@)C respectively. In steady state:

Three rods of equal length and equal area of cross section are connected end to end in series. The open end of the first rod (from left) is at a temperature of 300^@C and that of the last rod is at 20^@C in steady state. If the thermal conductivities of rods from left to right are in the ratio of 1: 3: 4, then find the temperatures of both the junctions.

Two bars of same length and same cross-sectional area but of different thermal conductivites K_(1) and K_(2) are joined end to end as shown in the figure. One end of the compound bar it is at temperature T_(1) and the opposite end at temperature T_(2) (where T_(1) gt T_(2) ). The temperature of the junction is

Two rods of same length and cross section are joined along the length. Thermal conductivities of first and second rod are K_(1) and K_(2) . The temperature of the free ends of the first and seconds rods are maintained at theta_(1) and theta_(2) respectively. The temperature of the common junction is
