| Mach number. |
|
It has been the practice in the valve industry to use the Mach number at the valve outlet to determine the velocity limitation in a compressible flow application. The fluid Mach number is defined as the ratio of fluid velocity over the velocity of sound in a given fluid.A high outlet Mach number in control valves is an indication of high stream power and results in high noise level, induced vibration and erosion. The valve outlet Mach number should be limited to avoid these problems. |
