The temperature drop through a two layer furnace wall is `900^@C`. Each layer is of equal area of cross section. Which of the following actions will result in lowering the temperature `theta` of the interface?

Which of the following reactions takes place at higher temperature range (900 K-1500 K) in blast furnace ?

Which of the following furnaces can be used to get above 3000^(@)C temperature ?

Find the temperature of junction at B, if each rod has equal area of cross-section.

Find the temperature of junction at B, if each rod has equal area of cross-section.

Two rods are connected as shown. The rods are of same length and same cross sectional area. In steady state, the temperature (theta) of the interface will be -

The temperature drop through each layer of a two layer furnace wall is shown in Assume that the external temperature T_(10 and T_(3) are mainitained constant and T_(1)gtT_(3) If the thichness of the layers x_(1) and x_(2) are the same which of the following statements are correct .

A composite wall of area A is made of equal thickness of lead and iron having thermal conductivities K and 2K, respectively. The temperature on the two sides of the composite wall are 100^(@)C and 0^(@)C with the layer on the hotter side. Calculate the steady -state temperature of the lead-iron interface.
