Frequently
Asked Questions
Flow rate measures the volume of liquid or gas passing through a pipe, pump, or system over a specific period. Common units include GPM, L/min, L/s, and m³/h.
Different countries and industries follow different measurement systems. North American pump specifications often use GPM, while many international manufacturers use L/min or m³/h.
The SI unit is cubic metres per second (m³/s), although m³/h and L/s are commonly used in practical engineering applications.
Yes. It is useful for dewatering, drainage, mining, flood control, municipal water transfer, and industrial pumping applications.
