cseppek

Cseppek is the Hungarian word for drops. The plural cseppek refers to small quantities of liquid that separate from a larger body and are typically held together by surface tension, which often makes them approximately spherical when viewed in air.

Formation and properties: Drops form by processes such as shedding from a surface, atomization, spraying, condensation, or spraying in devices like nozzles and inkjet printheads. Their sizes range from micrometers to millimeters. Surface tension and viscosity influence their shape, stability, and evaporation rate. As they fall through air, drops experience drag and may deform or break up, and their behavior is described by concepts from fluid dynamics and aerosol science.

Contexts and uses: In meteorology, drops describe rain, mist, and dew, with size distributions affecting precipitation processes and optical properties of clouds. In daily life, drops occur as water, oil, or medicine droplets—examples include eye drops, nasal sprays, and cosmetic serums. In technology, drop-based systems are central to inkjet printing, aerosol formulations, spray cooling, and microfluidics, where droplets act as discrete units for mixing, reactions, or transport.

Health and safety: Droplets can carry substances or pathogens in airborne or bodily contexts, making droplet size and concentration relevant for exposure and transmission considerations.
