Average Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Average velocity, abbreviated as \(\bar {v}\) or \(v_a\), is the average of any given velocities where the acceleration is constant.  The calculation for average velocity with zero accleration is shown below. 

\(\large{ \bar {v}= \frac { 1  } { 2 }  \left( v_i + v_f   \right)   }\)         

Where:

\(\large{ \bar {v}  }\) = average velocity

\(\large{ v_f  }\) = final velocity

\(\large{ v_i  }\) = initial velocity
