Metody měření hustoty automobilových olejů a paliv

The bachelor thesis deals with methods of liquid density measurement and appropriate gauges. The first part describes the density. The second part of the thesis presents the types of oils and fuels and their density. The thesis also focuses on the measurement methods and the gauges suitable for measuring the density of automotive oils and fuels. The last chapter is experimental and includes the measurement of several samples of automotive oils and fuels using digital hydrometer, Westphal balance and pycnometer. The graph with the density dependent on temperature is processed from the measured values. The professional literature is consulted considering the measured values of individual samples
