Solution: The tube for sensing the static pressure is known as static tube which surrounds the pitot tube that measures the **stagnation** pressure. **Stagnation** and Sonic Conditions It is convenient to choose some significant reference **point** in the flow where we can evaluate the constants in equations (12.70)-(12.72). Two such reference points are commonly used in compressible **fluid** dynamics. These are the **stagnation** conditions and sonic conditions. **Stagnation** Conditions. Equ. (6.1) holds for every **point** **in** a **fluid** flow whether steady or unsteady, compressible or incompressible. However, for incompressible flow, the specific mass ρ is constant and the equation simplifies to =0 ∂ ∂ + ∂ ∂ + ∂ ∂ z w y v x u (6.2) For two-dimensional incompressible flow this will simplify still further to =0 ∂ ∂. **Fluid Mechanics 4E -Kundu & Cohen**. × Close Log In.

One of the interesting features to determine for the resulting flow is the creation of a **stagnation** **point**, i.e., **point** where the velocity goes to zero. Reading time: 4 minutes. Velocity potential function and stream function are two scalar functions that help study whether the given **fluid** flow is rotational or irrotational. Both the functions provide a specific Laplace equation. The **fluid** flow can be rotational or irrotational flow based on whether it satisfies the Laplace equation or not. **Fluid Mechanics** Practice Problems; Combustion, Heat Transfer, Air Conditioning Practice ...

What is the result when the **fluid**’s kinetic energy during a **stagnation** process is transformed to enthalpy?. Introduction Flows that involve significant changes in density are called compressible flows. Therefore, ρ (x, y, z) must now be treated as a field variable rather than simply a constant.
