Finite Control Volume Analysis

Erhaltung der Masse im endlichen Kotrolvolumen
Erhaltung der Masse im endlichen Kotrolvolumen
The continuity equation is derived from the principle that the mass within a system remains constant. To analyze fluid movement, we observe the mass ...
Erhaltung der Masse in festem, nicht verformendem Kontrollvolumen
Erhaltung der Masse in festem, nicht verformendem Kontrollvolumen
The principle of conservation of mass states that, within a fixed control volume, any change in mass over time must be balanced by the flow of mass across ...
Erhaltung der Masse in bewegtem, nicht verformendem Kontrollvolumen
Erhaltung der Masse in bewegtem, nicht verformendem Kontrollvolumen
The conservation of mass is crucial in understanding the water flow in a rotating sprinkler system used for agricultural irrigation. The sprinkler ...
Linearer Impuls in der Lautstärke
Linearer Impuls in der Lautstärke
Newton's second law for a fluid system states that the rate of change of linear momentum in a flow with respect to time is equal to the sum of the ...
Anwendung der linearen Impulsgleichung
Anwendung der linearen Impulsgleichung
Water is flowing through a horizontal, U-shaped pipe bend. The cross-sectional area of the flow is 0.01 square meters, and the magnitude of the flow ...
Moment-of-Momentum-Gleichung
Moment-of-Momentum-Gleichung
The moment-of-momentum equation analyzes the torque produced by the rotating blades of a wind turbine. The moment-of-momentum equation is found by ...
Energieeinsparung im Regelvolumen
Energieeinsparung im Regelvolumen
The first law of thermodynamics states that the rate of change of total stored energy in a system equals the net rate of heat and work transferred into a ...
Anwendung der Energiegleichung
Anwendung der Energiegleichung
If the flow rate of a centrifugal pump that applies a pressure of 7500 joules per second to lift water from a reservoir at a lower level to a reservoir at ...
