Question 1

How do you convert gallons per hour to liters per hour?

Accepted Answer

Multiply US GPH by 3.78541. Example: 10 GPH = 37.85 LPH. UK gallon uses factor 4.54609.

Question 2

What is GPH used for?

Accepted Answer

Fuel consumption, irrigation drip systems, chemical dosing pumps, and small-scale fluid transfer.

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.
