# Average Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

## FORMULA

$$\bar {v}= \frac { \Delta x } { \Delta t }$$

Where:

$$\bar {v}$$ = average velocity

$$\Delta x$$ = position differential $$(x_f - x_i)$$

$$\Delta t$$ = time differential $$(t_f - t_i)$$

$$x_f$$ = final position

$$x_i$$ = initial position

$$t_f$$ = final time

$$t_i$$ = initial time
