Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da questa fonte: Virginia Tech Aerospace Engineering.
The Formula Explained
The calculation utilizes the hypersonic flow equations:
Pressure Ratio: \( \frac{p}{p_0} = \text{function of Mach number} \)
Temperature Ratio: \( \frac{T}{T_0} = \text{function of Mach number} \)
Glossary of Terms
- Mach Number: The ratio of the speed of the object to the speed of sound in the surrounding medium.
- Temperature (K): The absolute temperature in Kelvin.
- Pressure: The force exerted by the flow per unit area.
- Density: The mass per unit volume of the flow.
Frequently Asked Questions (FAQ)
What is hypersonic flow?
Hypersonic flow refers to the flow of air or gas that is traveling at speeds greater than five times the speed of sound (Mach 5).
How do I calculate the Mach number?
Mach number is calculated as the ratio of the object's speed to the speed of sound in the medium.
Why is temperature important in hypersonic calculations?
Temperature affects the speed of sound in the medium, which in turn affects flow properties like pressure and density.
Can this calculator be used for subsonic flow?
No, this calculator is specifically designed for hypersonic flow conditions.
What units are used in the calculations?
SI units are used, with temperature in Kelvin and pressure in Pascals.
