5 Questions
In which disciplines is fluid dynamics considered a subdiscipline?
Fluid dynamics is considered a subdiscipline of fluid mechanics in physics, physical chemistry, and engineering.
What are some of the subdisciplines of fluid dynamics?
Some of the subdisciplines of fluid dynamics include aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion).
What are some applications of fluid dynamics?
Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space, and modeling fission weapon detonation.
What properties of the fluid are typically calculated in a fluid dynamics problem?
In a fluid dynamics problem, properties of the fluid such as flow velocity, pressure, density, and temperature are typically calculated as functions of space and time.
What kind of laws are embraced in the systematic structure of fluid dynamics?
The systematic structure of fluid dynamics embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems.
