FAQ
What is the Exit Velocity?
Exit Velocity is the speed at which exhaust gases exit the primary nozzle of a propulsion system, such as a rocket or jet engine. Exit Velocity is usually measured using the Meter per Second for Speed. Note that the value of Exit Velocity is always positive.
Can the Exit Velocity be negative?
No, the Exit Velocity, measured in Speed cannot be negative.
What unit is used to measure Exit Velocity?
Exit Velocity is usually measured using the Meter per Second[m/s] for Speed. Meter per Minute[m/s], Meter per Hour[m/s], Kilometer per Hour[m/s] are the few other units in which Exit Velocity can be measured.
