====== GPH ====== GPH is commonly used in various applications such as pumps, filters, and irrigation systems to describe how quickly fluids are moved or processed. "GPH" stands for "Gallons Per Hour," a unit of measurement used to describe the flow rate or volume of liquid passing through a system over time. Here's how it relates to volume: GPH measures how many gallons of liquid flow through a system in one hour. For example, if a pump has a flow rate of 500 GPH, it means the pump moves 500 gallons of liquid every hour. **Converting GPH to other units:** * Litres Per Hour (LPH): To convert GPH to LPH, you can use the conversion factor where 1 gallon is approximately 3.78541 litres. Therefore: **Flow rate in LPH = Flow rate in GPH × 3.78541** * Cubic Feet Per Hour (CFH): To convert GPH to CFH, knowing that 1 gallon is approximately 0.133681 cubic feet helps. Thus: **Flow rate in CFH=Flow rate in GPH×0.133681**
