Two phase velocity calculation
WebCalculation between phase angle φ° in degrees (deg), the time delay Δ t and the frequency f is: Phase angle (deg) (Time shift) Time difference Frequency λ = c / f and c = 343 m/s at 20°C. Calculation between phase angle φ in radians (rad), the time shift or time delay Δ t, and the frequency f is: Phase angle (rad) WebThe slip ratio (or velocity ratio) in a two-phase flow is defined as the ratio of the velocity of the vapor phase to the velocity of the liquid phase. ...

WebThe result is a two phase mixture (vapor and liquid) at the valve outlet and in the downstream piping. Velocity of this two phase flow is usually very high and results in the possibility for erosion of the valve and piping components.
