 Aerodynamic Drag Equation and Calculator Aerodynamic Drag is the opposing fluid drag force that acts on any moving solid body
 Continuity Equation Continuity equation is a mathematical expression of the principle of conservation of mass.
 Properties of Fluids A fluid is any substance which flows because its particles are not rigidly attached to one another.
 Buoyancy Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object.
 Compressibility Compressibility is the measure of the change in volume a substance undergoes when a pressure is exerted on the substance.

 Pascal's Law Pascal's law or the principle of transmission of fluidpressure
 Control Volume Control volume is a mathematical abstraction employed in the process of creating mathematical models of physical processes.
 Volumetric Flow Rate volumetric flow rate (V ) of a system is a measure of the volume of fluid passing a point in the system per unit time.
 Mass Flow Rate Mass flow rate of a system is a measure of the mass of fluid passing a point in the system per unit time
 Conservation of Mass Mass flow rates into a control volume are equal to all mass flow rates out of the control volume plus the rate of change of mass within the control volume.
 SteadyState Flow Steadystate flow refers to the condition where the fluid properties at any single point in the system do not change over time.
 Continuity Equation Continuity equation is a mathematical expression of the principle of conservation of mass.

 TwoPhase Fluid Flow Twophase flow occurs in a system containing gas and liquid with a meniscus separating the two phases
 Flow Instability Unstable flow can occur in the form of flow oscillations or flow reversals.
 Pipe Whip If a pipe were to rupture, the reaction force created by the high velocity fluid jet could cause the piping to displace and cause extensive damage
 Water Hammer Water hammer is a liquid shock wave resulting from the sudden starting or stopping of flow.
 Pressure spike Pressure spike is the resulting rapid rise in pressure above static pressure caused by water hammer.
