Navier-Stokes equation The Navier-Stokes equation is the fundamental equation of fluid dynamics that models the flow in everything from bathtubs to oceans. In one of its many forms (incompressible, viscous flow), the equation is ρ ( ∂ V ∂ t + ( V ⋅ ∇ ) V ) = − ∇ p + μ ( ∇ ⋅ ∇ ) V . In this notation, V = ( u, v , w ) is the three-dimensional velocity field, p is the (scalar) pressure, ρ is the constant density of the fluid, and μ is the constant viscosity. Write out the three component equations of this vector equation. (See Exercise 40 for an interpretation of the operations.)

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.

The figure shows an overhead view of a 0.026 kg lemon half and two of the three horizontal
forces that act on it as it is ona frictionless table. Force F has a magnitude of 3 N and is at
