What does the term "flow rate" indicate in plumbing systems?

The term "flow rate" specifically refers to the volume of water that flows through a plumbing system over a specified time period, usually measured in liters per minute. This measurement is crucial for understanding how much water is available for use at any given moment, influencing the performance of faucets, showers, and other fixtures. Knowing the flow rate helps plumbers design systems that meet the demand for hot water and ensure efficiency, preventing issues like insufficient pressure or inadequate supply for appliances.

Understanding the flow rate is essential for various applications, such as sizing pipes, selecting pumps, and ensuring that water heating systems can deliver the desired temperature quickly. Also, a higher flow rate may be required for certain applications like filling a bathtub quickly or providing adequate water supply for multiple fixtures in use simultaneously.
