What is the kinematic viscosity of diesel?

No. 2 diesel fuel has a viscosity in the range of 2.5–3.2 cSt at 40°C, and biodiesel consisting of the methyl esters of soybean oil has a viscosity between 4.2 and 4.6 cSt (1,3–6).

What is kinematic viscosity of fuel?

Kinematic viscosity is a measure of a fluid’s internal resistance to flow under gravitational forces. It is determined by measuring the time in seconds, required for a fixed volume of fluid to flow a known distance by gravity through a capillary within a calibrated viscometer at a closely controlled temperature.

What is kinematic viscosity formula?

The units of kinematic viscosity are established on time and area. It is the ratio of the dynamic viscosity to its density, a force independent quantity. It is the ratio of the area of time; henceforth it is m22/s or ft22/s. The kinematic viscosity formula is expressed as, ν = μ/ρ

What are the specifications of The D446 kinematic viscometer?

D446 Specifications and Operating Instructions for Glass Capillary Kinematic Viscometers D1217 Test Method for Density and Relative Density (Specific Gravity) of Liquids by Bingham Pycnometer D1480 Test Method for Density and Relative Density (Specific Gravity) of Viscous Materials by Bingham Pycnometer

How is kinematic viscosity measured in used oil?

This new test method (ASTM D7279 – Test Method for the Determination of Kinematic Viscosity of Transparent and Opaque Liquids by Automated Houillon Viscometer) has specific provisions for rapid measurement of in-service engine oils. It differs from D445 in that only a single determination (drop) is made per sample.

What does the ASTM designation number D445 mean?

An ASTM designation number identifies a unique version of an ASTM standard. Active Standard ASTM D445 | Developed by Subcommittee: D02.07 5.1 Many petroleum products, and some non-petroleum materials, are used as lubricants, and the correct operation of the equipment depends upon the appropriate viscosity of the liquid being used.

How to calculate the dynamic viscosity of a liquid?

The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. Note 1: For the measurement of the kinematic viscosity and viscosity of bitumens, see also Test Methods and .
