Finding the properties of crude oil after addition of nano particle is considered in this work. The experiments are held to investigate the effect of nano particles on the physical properties of two kinds of heavy crude oil (API =21.45), medium crude oil (API=27.9) and light crude oil (API= 32.95). The ferric oxide nano particle decreases the viscosity of oil sample B about 11.4%, averagely comparing with the viscosity of oil sample B without the nano. Also, the empirical results illustrate the variation of temperature from 50°C to 90°C for medium crude oil (Sample C). The experimental results show, the decreasing in viscosity values for nano and simple medium oil. The obtained results show the trend of viscosity for nano oil is severely than simple oil. The average decreasing in the viscosity values are measured as 12.9% comparing with the viscosity of simple oil. All of the obtained results show the nano particles can improve the heat transfer rate in the text of crude oil. So, the trends of all of the experimental graphs are decreasing.
