With two separate forms for incompressible and compressible fluids, its parameters are the pressure, velocity, density, and kinematic viscosity of the substance being described.  
A convection term is contained in its material derivative, the time derivative of the fluid velocity in this equation.  With two separate forms for incompressible and compressible fluids, its parameters are the pressure, velocity, density, and kinematic viscosity of the substance being described.  It can be obtained by combining the equations for kinematics and constitutive relation into the equation of motion.  Used to model turbulent flow or describe the motion of a non-turbulent fluid, this is, FTP, what fluid dynamical equation named after two scientists?
