Experimental data are presented which verify the least Reynolds number at which transient disturbances are amplified and transition to turbulence occurs. The least critical Reynolds number data shows good agreement with stability analysis predictions performed by Curle. The observations reported were obtained from jets formed by supply nozzles with aspect ratios of 1. The range of aspect ratios was limited around unity because the results are then directly applicable to microminature fluid amplifiers. In addition to critical Reynolds number determination, data are presented that gives the distance at which transition to turbulence occurs for several typical geometries. Author
