Objective: The objective of this lab is to construct a student to be more advanced and competent in measuring oil gravity, viscosity, bottom sediment, and water. Introduction: Crude oil properties such as oil gravity, viscosity, bottom sediment, and water are used all over the United States throughout the petroleum industry for proposing oil transportation and facilities. In the oil industry we use API Gravity to express the density of oil, which is defined as a measure of how heavy or light petroleum liquid is compared to water. If API Gravity is greater than 10, it is lighter and floats on water, if less than 10, it is heavier and sinks to the bottom. The oil is measured by an instrument called a hydrometer and then classified as a certain grade of oil. Viscosity is a very important property in this industry because it a measure of the resistance to flow, which is being distorted by either shear stress or extensional stress. Pressure and temperature play a big role because viscosity increases with pressure and decreases with temperature. There are two different viscosityies that rae related through density which are kinematic and dynamic viscosity. Dynamic viscosity, also called absolute viscosity, verifies the
