Summary

Obsahem předmětu je seznámit se podrobně s vybranými vlastnostmi kapalin, se zaměřením na kapaliny používané v hydraulických systémech. Probírají se postupně fyzikální vlastnosti kapalin (viskozita, stlačitelnost atd.), chemické vlastnosti (termooxidační stálost, korozivní působení na kovy, agresivita vůči pryžím a plastům), reologické vlastnosti, provozní vlastnosti (mazací schopnost apod.) a ekologické vlastnosti. Dále se studenti podrobně seznámí s jednotlivými druhy kapalin, jako jsou zejména: voda, minerální oleje, těžkozápalné kapaliny, ekologicky šetrné kapaliny.
