Pump Rate Calculator
Convert between SPM, GPM, circulation time and annular velocity for drilling operations.
Key Relationships:
Flow (GPM) = SPM × Pump Output (gal/stroke)
SPM = Flow (GPM) ÷ Pump Output (gal/stroke)
Circulation Time (min) = System Volume (bbl) × 42 ÷ Flow (GPM)
Flow (GPM) = SPM × Pump Output (gal/stroke)
SPM = Flow (GPM) ÷ Pump Output (gal/stroke)
Circulation Time (min) = System Volume (bbl) × 42 ÷ Flow (GPM)
