![]() ![]() There is an option of embedding the calculator. Used formulas are listed below the calculator. “State system for ensuring the uniformity of measurements for the density of oil. Formulas are taken from Russia’s GOST R 8.610-2004. The recalculation of the density of oil for different temperature and pressure values. ![]() Values are determined at existing temperatures and corrected to 15☌ or 60☏ by means of a series of calculations and international standard tables. This test method covers the laboratory determination using a glass hydrometer in conjunction with a series of calculations of the density, relative density, or API gravity of crude petroleum, petroleum products, or mixtures of oil and nonpetroleum products generally handled as liquids, and having a Reid vapour pressure of 101.325 kPa (14.696 psi) or less. Lighter crude oil may require special handling to prevent vapour losses.ĪSTM D1298-12: Standard Test Method for Density, Relative Density (Specific Gravity), or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method. Density is a property of solids and fluids that provides a measure of mass contained in a unit volume. ![]() This test method was evaluated in interlaboratory study testing using crude oils in the range of 0.75 g/mL to 0.95 g/mL. This test method applies to crude oils with high vapour pressures, provided appropriate precautions are taken to prevent vapour loss during the transfer of the sample to the density analyser. This test method covers the determination of the density, relative density, and API gravity of crude oils that may be handled generally as liquids at test temperatures between 15 ☌ and 35 ☌ utilizing either manual or automated sample injection equipment. Slug Per Cubic Foot (slug/ft 3) has a dimension of ML-3 where M is mass, and L is length. This unit is commonly used in the UK, US unit systems. Here is a simple density (and viscosity) units conversion tool:ĪSTM D5002-19: Standard Test Method for Density, Relative Density, and API Gravity Of Crude Oils By Digital Density Analyser. Slug Per Cubic Foot (slug/ft 3) is a unit in the category of Density.It is also known as slugs per cubic foot, slug/cubic foot. This is not always the case, as some Group IV base oils can have a higher density than water, effectively causing the oil to sink in the water. This is why if you have a moisture problem in your lube system that the water settles to the bottom of the sump and is drained out first whenever the plug is pulled, or the valve is opened. If the density of an object is less than that of water, then that object will float. Just simply enter value 1 in Water Density and see the. Feel free to use our online unit conversion calculator to convert the unit from Water Density to Pound/Cubic Inch. This means that most oils will float on water as they are lighter by volume. The answer is one Water Density is equal to 0.036127292000084 Pound/Cubic Inch and that means we can also write it as 1 Water Density 0.036127292000084 Pound/Cubic Inch. In oils, it is usually indicated in the temperature of +15☌ or +20☌, in units kg/m3. The density of most oils will range between 700 and 950 kilograms per cubic meter (kg/m3). Most systems are designed to pump a fluid of a specific density, so as the density begins to change, the pump’s efficiency begins to change as well. On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular force is applied to the fluid.Density plays a critical role in how lubricant functions and how machines perform. When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed. The larger the force or stress needed to move the plate, the more viscous the fluid is. g In the U.S., density is often given as pounds per cubic foot, lb/ft³ Since g 32.2 ft/sec² (9.81 m/sec²), the specific weight of water is 32.2 x 1.94 slugs 62. ![]()
