mechanical; → mixing.

mechanical power
  توان ِ مکانیکی   
tavân-e mekâniki (#)

Fr.: puissance mécanique   

The → rate at which → work is done by a → force. In other words, → mechanical energy per unit time. Mechanical power is expressed in units of joules/sec (joules/s) or a watt (W) in the → mks system.

bâd-e mekâniki

Fr.: vent mécanique   

A process in which matter is shed into a → Keplerian disk from a star rotating at the → critical velocity.
