We have made an experimental set-up to measure thermal conductivity of oil. Experimental setup is designed in such a way that the accuracy it obtain is kept at the same level, while the cost of the experimentation is reduced to 1/10th of other equivalent model available in market. Modifications done are in positioning of the thermocouple, mass flow rate of the water through the water jacket and its arrangement, the design and placement of heater, the positioning oil pocket for oil, use of less costly and widely available material, etc.
