Two city councilmen want to ban aluminum bats, alarmed at the "exit velocity" of the batted ball.
The loss of energy due to this higher exit velocity is commonly called the carry over velocity or leaving loss.
Lighter pellets have less kinetic energy than their heavier pellets, despite their higher exit velocity.
The cooling air exit from the oil and coolant radiators was reduced in area to match the exit velocity to the local flow.
However, the exit velocity is axial in Kaplan runner, while it is the radial one in all other runners.
Except they were, at their exit velocity, which was faster than she'd have chosen.
Rocket engine nozzles discusses how to calculate the exit velocity from nozzles used in rocket engines.
Specifically, the committee recommended that the batted-ball exit velocity of aluminum bats be reduced from 113 miles per hour to 93.
A good thing, considering they will need as much exit velocity as their nerves can bear.
The high exit velocity of the jet enables a relatively large separation between the print head and the substrate, typically 2-5 mm.
