Calculation

1. Plot the variation of temperature along the length of the specimen (T vs x), from the graph to obtain the slope,

2. Mass flow rate of cooling water,

3. Heat carried away by cooling water,

4. C.S. area of metal rod,

5. Determine the value of thermal conductivity 'k' using energy balance,

Heat conducted through the metal rod = Heat carried away by cooling water

Note: The value of slope will be negative owing to direction of heat transfer
