Question

The stagnation pressure in a mach 2 wind tunnel operating with air is 900 kpa. A 1.0 cm diameter

Answer 1

Answer:

Step-by-step solution:

Step 1 of 5

Obtain specific heat ratio of air from Table 1.8, "Approximate Physical Properties of Some Common Gases at Standard Atmospheric Pressure (SI Units)," from the text book.

Specific heat ratio,

Calculate the pressure in the wind tunnel by using the following expression:

Here, the pressure in the wind tunnel is p, the stagnation pressure is , and the Mach number is Ma.

Substitute 1.4 for k, 2 for Ma, and 900 kPa for .

Answer 2

Answer:

In fluid dynamics, stagnation pressure (or pitot pressure) is the static pressure at a stagnation point in a fluid flow. At a stagnation point the fluid velocity is zero. In an incompressible flow, stagnation pressure is equal to the sum of the free-stream static pressure and the free-stream dynamic pressure.
