Hallo allemaal,
Ik ben opzoek naar (zoals in de titel al te lezen) de uitzettingscoefficient van o.a. slaolie, olijfolie, zonnebloemolie etc. Een van de drie is voor mij genoeg!
Alvast bedankt!

Groeten, maarten

Ik vind dit op klik voor olijfolie:

Density

0.914 - 0.919 g/cm3 (cold-pressed) [1]
0.920 - 0.925 g/cm3 (hot-pressed) [1]


All fats and oils have a particular density (approx. 0.9 g/cm3). With a rise in temperature, however, density diminishes, thereby leading at the same time to an increase in volume. This behavior is described by the coefficient of cubic expansion and is known as thermal dilatation.

The coefficient of cubic expansion amounts to: g = approx. 0.00072įC-1

As a rule of thumb, oils may be expected to increase in volume by 1% of their total volume for each 14įC temperature increase.

When filling the barrels or tanks, attention must however be paid to the expansion behavior of the cargo in the event of a rise in temperature (risk of bursting of barrels).


en dit op klik nogmaals voor zonnebloemolie:

Density

0.918 - 0.927 cm3 [1]
0.918 - 0.926 cm3 [2]
0.917 cm3 [11]
