Question 1

How do you convert liters per second to GPM?

Accepted Answer

Multiply L/s by 15.8503. Example: 5 L/s = 79.25 GPM.

Question 2

Which is larger, GPM or LPM?

Accepted Answer

GPM is larger. 1 GPM = 3.785 LPM. US gallon (3.785 L) > 1 liter.

Question 3

How does pipe diameter affect flow rate?

Accepted Answer

Flow rate is proportional to the square of diameter. Doubling pipe diameter quadruples potential flow rate at the same pressure.

Question 4

What's the difference between volume and mass flow rate?

Accepted Answer

Volume flow (gallons/min) ignores fluid density. Mass flow (kg/s) accounts for density, important when density changes with temperature or pressure.
