Fluid dynamics
Fluid dynamics kan jedhamu gossa barnotta fluid mechanics jalatti argamu yoo ta'u, kan qo'attus wa'ee "fesashi" fi gazii ademsaa (lola'u) kessa jiranni (fluids) qo'atta. Kunii immo ofii kessatti qoqqodama qaba, isaanis aerodynamics - qo'anno ademsaa gazii fi qillensa fi hydrodynamics - qo'anno ademsaa "fesashi" jedhamanii dha. Fluid dynamicsiin fayyidaa bayee qaba, isaanis humna fi momentii bariftotta (xuyuraa, jetii...) lakka'u, mass flow rate petroleumiin tuboo kessatti ademmu kessatti qabu barbadu, wa'ee dedebi'ee dhufuu halla qillensa duratti bekku, wa'ee nebulae bakka duwwa interstellar kessatti argamuu bekuuf, midhagsisuu tokasisuu meshaa warranaa tokka'anii kessatti fayyida qaba. Jechonni fluid dynamics kessatti argamii tokko tokko traffic engineering kessatti fayyida qabu, kunis trafficii akka waan lola'utti fudhachuun.
Fluid dynamics offers a systematic structure that underlies these practical disciplines and that embraces empirical and semi-empirical laws, derived from flow measurement, used to solve practical problems. Fluid dynamics kessatti rakkoleen argaman kan hikkaman ammalla (property) "fluid" (fesashi) kan akka velocity, dhibaa, density fi temprature isaanii yeroo (time) fi bakka irratti hunda'anii lakka'un.
