Experiment to determine the specific heat of oils
Abstract
During machining process cutting fluids are used to minimize the heat that is developed between tool, work piece and the chip. Heat absorption capacity of any cutting fluid used is measured by specific heat. Higher the specific heat better will the heat absorption capacity. This paper discusses the experimental procedure used to measure the specific heat of Neem oil, Honge (Karanja), Sunflower oil and Petroleum based oil (Hydro 68). This experiment is a function of temperature with respect to time. This method is validated by measuring the specific heat of distilled water, since the standard specific heat value of distilled water is known. The results show that Specific Heat of Neem Oil is good compared to Honge and sunflower Oil, but less compared to Petroleum oil (Hydro 68) which is used as cutting fluid for drilling operation in Industries after mixing with water.
