Abstract
Laser velocimetry measurements are presented for transitional pipe. It is shown that a) scaling phenomena appear well before the transition to fully developed turbulence is completed, b) multifractal structures are not a characteristic of fully developed turbulence, but they are already present at Reynolds numbers as low as 1500.
