Av (ft/min) = \frac{24.5 \cdot Q}{D h^{2} - D p^{2}}

$"Av (ft/min)" = (24.5*Q)/(Dh^2 - Dp^2)$

(Q) Pump output

$(Q)"Pump output"$

(D h) Inside Diameter

$(Dh)"Inside Diameter"$

(D p) Outside Diameter

$(Dp)"Outside Diameter"$

The formula for the Annular Velocity is :

$A V = \frac{24.5 \frac{ft}{g a l \cdot {in}^{2}} \cdot Q}{D h^{2} - D p^{2}}$ $AV =(24.5 "ft"/(gal*"in"^2) * Q )/(Dh^2 - Dp^2)$

where:

Volume Pumped over time by Pump Flow-rate
Time to Pump Deadweight Tonnage: Computes time to pump an amount of oil measured by DWT at a pumping rate. It also returns the volume pumped in barrels.
Time to Pump Volume by Flow-rate: Computes the time to pump an amount of fluid (e.g., oil) based on a volume and pump rate.
Duplex Pump Output: Barrels per stroke from a duplex pump.
Triplex Pump Output: Barrels per stroke from a triplex pump.
Quintuplex Pump Output: Barrels per stroke from a quintuplex pump.
Barrel Production: Computes the total volume (barrels) produced over a period of time based on the production rate and duration.
Annular Velocity: Compute the fluid flow velocity, based on the flow rate and pipe dimensions.
Mud Buoyancy: Computes the buoyancy in mud
Volume of a Pipe: Computes the volume of a pipe.
Weight of Pipe Contents: Computes the weight (mass) based on density and pipe dimensions.
Density of Oil:
- Crude at (48° API): 790.0 kg/m³
- Crude at (40° API): 825.0 kg/m³
- Crude at (35.6° API): 847.0 kg/m³
- Crude at (32.6° API): 862.0 kg/m³
Energy in Crude Oil: 5800000.0 BTU/bbl
