t/Year [ac·ft/y]

Acre-foot per year [ac·ft/y] is a unit of volumetric flow rate commonly used in hydrology, water resource management, and irrigation planning. One acre-foot represents the volume of water required to cover one acre of land to a depth of one foot, which is approximately 1,233 cubic meters or 325,851 gallons. When expressed per year, ac·ft/y quantifies the total water volume delivered, used, or available over a 12-month period. This unit is particularly useful for managing large-scale water supplies, such as reservoirs, rivers, or agricultural irrigation systems, providing a standardized measure to estimate annual water availability and consumption. For example, an irrigation system supplying 500 ac·ft/y delivers enough water to cover 500 acres to a depth of one foot over a year. It is also used to plan municipal water supply, allocate water rights, and forecast long-term resource needs. Compared to daily or monthly flow units, acre-foot per year gives a macro-level perspective, suitable for long-term planning, resource management, and sustainability assessments. Using ac·ft/y enables engineers, hydrologists, and policymakers to monitor, manage, and optimize water resources, ensuring efficient allocation and conservation for agricultural, municipal, and industrial use.

Second [gal (US)/s]

Gallon per second (US) [gal (US)/s] is a unit of volumetric flow rate that measures the volume of liquid passing through a system every second, using the US liquid gallon as the standard. One US gallon equals approximately 3.785 liters, so gal (US)/s quantifies how many gallons flow each second, making it suitable for applications requiring very high flow rates. This unit is commonly used in hydraulics, large-scale water distribution, industrial processes, and emergency systems where rapid fluid movement must be monitored and controlled accurately. For instance, in water supply networks or dam releases, gal (US)/s helps engineers design pipelines, pumping stations, and valves to deliver large volumes of water efficiently. In industrial manufacturing, it regulates the flow of liquids in processes like cooling, chemical mixing, or fuel transfer, ensuring smooth and safe operation. Compared to gal/min or gal/h, gallon per second provides real-time measurement and control, enabling immediate response to changes in flow demand. Using gal (US)/s allows engineers, technicians, and managers to measure, manage, and optimize high-volume fluid flow, ensuring efficiency, safety, and reliable operation in critical municipal and industrial applications.
