intake and ambient velocity

free stream wind speed | free stream wind velocity

tangential velocity [ flow velocity | cross-flow velocity ]

Darcy velocity [ darcian velocity | specific discharge ]

inlet velocity | suction velocity

free speed [ free-flow speed | cruising speed ]

outflow speed

flow velocity | current velocity | stream velocity

The reference sound is assessed at a single point in one discrete gear, simulating an acceleration condition starting with an entry speed at vaa equal to 50 km/h and assuming an exit speed at vbb equal to 61 km/h.

The coastdown time Δtai corresponding to the specified speed vj shall be measured as the elapsed time from the motorcycle speed vj+Δv to vj-Δv.

In amendments 7 and 10 the deadlines were brought into line with those in amendment 6, which was accepted, so as to achieve a phased-in implementation of the directive over 2, 3, 4 and 5 years, i.e. implementation by the Member States and installation of speed limitation devices in new vehicles within two years of the entry into force of the directive, retro-fitting of speed limitation devices into vehicles which are used in international transport within three years, retro-fitting of speed limitation devices into vehicles which are exclusively used for domestic transport within four years and the expiry of any national exemptions within ...[+++] five years.

What we are proposing here is that the directive should apply five years after it enters into force and, secondly, that the European Commission should submit a study eighteen months after the directive enters into force on so-called intelligent speed adaptation systems so that we can see if we can use these systems to differentiate speeds depending on the circumstances and, of course, if we can have even lower speeds in urban areas.
