Kerosene kinematic viscosity

Kerosene and gasoline are pumped successively at 1.1 m/s through a 25.5-cm ID pipeline 1000 km long. Calculate the 5/95%-95/5% contaminated width at the exit of the pipe given that the kinematic viscosity for the 50/ 50% mixture is... 

The Ferret is recommended for liquids with kinematic viscosities greater than or equal to 4 centistokes (cst) at 55°F. Compatible liquids include fresh gasoline, JP4, JP5, kerosene, diesel... 

Determine the kinematic viscosity of the oil Use Fig. 6.1 and Table 6.2 or the Hydraulic Institute—Pipe Friction Manual kinematic viscosity and Reynolds number chart to determine the kinematic viscosity of the liquid. Enter Table 6.2 at kerosene and find the coordinates as X = 10.2, Y = 16.9. Using these coordinates, enter Fig. 6.1 and find the absolute viscosity of kerosene at 65°F as 2.4 cP. Using the method of Example 6.2, the kinematic viscosity, in cSt, equals absolute viscosity, cP/specific gravity of the liquid = 2.4/0.813 = 2.95 cSt. This value agrees closely with that given in the Pipe Friction Manual. 

The kinematic viscosity of Jatropha oil at 40 C was 31.5 cSt. After transesterification to the Jatropha methyl esters, viscosity was reduced to 4.4 cST. The viscosities of kerosene and diesel No.2 were 2.35 cSt and 4.16 cSt respectively. Thus JCME has a viscosity 1.9 times that of kerosene and 1.06 that of diesel No.2. At 20 C, the density of JCME was found to be 1.1 times that of kerosene and 1.03 times of that of diesel No.2. 

The very mobile are liquid very light and volatile solutions of organic matter (p < 0.7 g-ml ) with kinematic viscosity lower than for water (< 1.0 cm -s" )- These are light solvents, oils or petroleum products (gasoline, kerosene) capable of relative easily floating to the surface. 

Kinematic viscosity of kerosene is 0.6 cSt. Therefore, viscosity is not a critical factor because it is less than 5 to 10 cSt. 

Kinematic viscosity may be determined directly by means of Ubbelohde, FitzSimmons modification, or modified Ostwald viscosimeter pipettes (D445). A series of these pipettes which cover the entire useful range of viscosity may be suspended in a single constant-temperature bath. Great accuracy is possible with these instruments, and a somewhat smaller sample is satisfactory, but each instrument must be calibrated. The pipette method must be used for gasoline, naphthas, or kerosene, because turbulent rather than streamline flow occurs in the large orifices of the Saybolt equipment. The viscosity of kerosene is sometimes determined in the Saybolt thermoviscosimeter, and thermoviscosity (at 60 F) is related to the kinematic and Saybolt Universal viscosity (at 60 F) approximately as follows ...
