Crude Oil Petroleum Viscosity Gravity Density

Overview

Engineering reference data for Crude Oil Petroleum Viscosity Gravity Density in fluid mechanics.

Key Formulas

Reynolds Number

$Re = \frac{\rho v D}{\mu}$

Ratio of inertial to viscous forces — determines flow regime.

Bernoulli's Equation

$P + \frac{1}{2}\rho v^2 + \rho g h = \text{const}$

Conservation of energy for steady, inviscid, incompressible flow.

Continuity Equation

$A_1 v_1 = A_2 v_2$

Conservation of mass for incompressible flow.

Darcy-Weisbach

$\Delta P = f \frac{L}{D} \frac{\rho v^2}{2}$

Pressure drop due to friction in a pipe.

Data Sources and Background

The crude oil property data, including viscosity, gravity, and density, is based on over 120 crude oil assays from BP, ExxonMobil, and Statoil (2008–2017), representing globally sourced crudes. Related studies also explore correlations such as metal content (nickel, Ni, and vanadium, V) as a function of gravity.
