In plumbing, what does the abbreviation "GPM" stand for?

  1. Gallons Per Month

  2. Gallons Per Minute

  3. Gallons Per Meter

  4. Gallons Per Machine

The correct answer is: Gallons Per Minute

The abbreviation "GPM" stands for "Gallons Per Minute." This term is commonly used in plumbing and fluid dynamics to measure the flow rate of water or other liquids. Understanding GPM is crucial for determining the capacity of plumbing fixtures, designing an efficient plumbing system, and ensuring that water supply meets the demands of various applications, such as showers, faucets, and irrigation systems. This measure helps plumbers calculate how much water can be delivered or removed within a specific time frame, which is essential for maintaining proper water pressure and flow in residential and commercial settings.
