Query: Driving determines the dynamics in transitional pipe flow   The understanding that pipe flow is governed by a single parameter, the
Reynolds number $Re$, is well accepted. Here we provide extensive experimental
evidence that in addition to $Re$, knowledge of the flow's driving mechanism is
essential to properly understand the dynamics and stationary states of pipe
flow during the transition to turbulence.
