"Liters per second" (L/s) is a unit of measurement that indicates the flow rate of a liquid. It tells us how many liters of liquid pass a certain point in one second. This measurement is commonly used in various fields, such as engineering, environmental science, and plumbing, to assess the efficiency of water systems or the capacity of pumps. For example, if a water pump has a flow rate of 5 L/s, it means that the pump can move 5 liters of water every second. Understanding flow rates in L/s helps in designing systems that require precise water management, such as irrigation systems or water treatment plants.
