Flow Rate Conversion Table
Description of Flow Rate
Flow rate is a measure of the volume of fluid passing through a point per unit time. It is essential in various industries to ensure systems operate efficiently. This article offers an overview of flow rate conversion between GPM and CFM, including calculation methods and a comprehensive table for reference.
GPM and CFM
GPM (Gallons Per Minute)
Gallons Per Minute (GPM) is a unit of flow rate used primarily for liquids. It measures how many gallons of liquid flow each minute, which is crucial for applications like water supply systems and irrigation.
CFM (Cubic Feet Per Minute)
Cubic Feet Per Minute (CFM) measures the flow rate of gases, particularly air. It indicates the volume of air flowing each minute, which is vital for HVAC systems and industrial ventilation.
Flow Rate Conversion Table
Calculating flow rate involves determining the volume of fluid or gas passing through a system over time. Understanding both GPM and CFM is crucial for accurate measurements and system design. Proper calculations ensure that systems are neither overburdened nor underperforming, leading to optimal performance and energy efficiency.
Below is a table that converts flow rates between GPM and CFM, facilitating quick reference and accurate calculations. 1 GPM ≈ 0.127 CFM.
