Fluid Dynamics topics include: Euler and bernoulli equations of motion, bernoulli applications, newtons first and second law, navier strokes equation, impulse and moment of momentum equation. Fluid dynamics is a branch of physics, physical chemistry, and engineering that studies the flow of liquids and gases. It has several subdisciplines, including aerodynamics and hydrodynamics. Factors that influence the flow pattern of liquids and gases include: The fluid's characteristics, such as density, compressibility, and viscosity The speed of the flow The shape of the solid...
