# Annular Velocity Calculator, Formula, Annular Velocity Calculation

## Annular Velocity Calculator:

Enter the values of Pump Output PO(bbl/min) & Annular capacity AC(bbl/ft) to determine the value of Annular Velocity AV(ft/min).

 Enter Pump Output: bbl/min Enter Annular Capacity: bbl/ft Result – Annular Velocity: ft/min

## Annular Velocity Formula:

The Annular Velocity AV(ft/min) in feet per second is equal to the Pump Output PO(bbl/min) in bbl per minute to multiply the Annular capacity AC(bbl/ft) in bbl per feet.

The Equation of Annular Velocity can be writtern as,

AV(ft/min) = PO(bbl/min) * AC(bbl/ft)

Here,

AV(ft/min) = Annular Velocity in feet per second

PO(bbl/min) = Pump Output in bbl per minute

AC(bbl/ft) = Annular capacity in bbl per feet

### Calculation For Annular Velocity:

1)Determine the Annular Velocity and given for Pump Output = 10.5bbl/min , Annular capacity = .25 bbl/ft.

AV = PO * AC

AV = 10.5 * .25

AV = 2.625ft/second.

2)Determine the Annular capacity  and given for Pump Output = 10.5bbl/min , Annular Velocity = 2.625ft/second.
