  Bernoulli equation for incompressible, smooth fluid flow.
An important and highly useful special case is where friction is ignored and the fluid is incompressible.
The absence of friction means that the fluid flow is steady.
That is, the fluid does not stick to the pipe sides and has no turbulence.

 Fluid_dynamics
Fluid dynamics is the subdiscipline of fluid mechanics that studies fluids (liquids and gases) in motion.
Flows of liquids with pressure variations much smaller than those required to cause phase change (cavitation), or flows of gases involving speeds much lower than the isentropic sound speed are termed incompressible.
For flow of gases, to determine whether to use compressible or incompressible fluid dynamics, the Mach number of the problem is evaluated.

The foundational axioms of fluid mechanics are the conservation laws, specifically, conservation of mass, conservation of momentum (also known as Newton's second law), and conservation of energy These are based on classical mechanics and are violated in relativistic mechanics.
The central equations for fluid mechanics are the Navier-Stokes equations, which are non-linear differential equations that describe fluid flow.
Another often used model, especially in computational fluid mechanics, is to use the Euler equations far from the body and the boundary layer equations close to the body.

Computational fluid dynamics (CFD) is the use of computers to analyze problems in fluid dynamics.
It is possible to directly solve the Navier-Stokes equations for laminar flow cases and for turbulent flows when all of the relevant length scales can be contained on the grid (a Direct numerical simulation).
The volume occupied by the fluid is divided into discrete cells (the mesh).

 High-Order Methods for Incompressible Fluid Flow - Cambridge University Press
This book considers the range of mathematical, engineering, and computer science topics that form the foundation of high-order numerical methods for the simulation of incompressible fluid flows in complex domains.
It could be recommended to computer scientists, engineers, and applied mathematicians interested in developing software for solving flow problems.
It could be also recommended to graduate students that have a background in fluid mechanics and numerical methods." Zbl.

 Moldwin's Time line of Solar Terrestrial Physics
Navier (in 1821) and Stokes (some 20 years later) independently developed the differential equations describing incompressible fluid flow.
The equation is now known as the Navier-Stokes equation and is the basis of fluid dynamics.
