Calculation Method
This calculator uses the correct formula for Mach number:
Mach Number = Flow Velocity / Sonic Velocity
Where:
- Flow Velocity = (Flow Rate in kg/s) / (Density × Pipe Cross-sectional Area)
- Sonic Velocity = √(γ × P_absolute / ρ)
Absolute pressure is calculated as: P_absolute = P_gauge + 1.01325 bar
