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 [bbl (US)/s]

Barrel per second (US) [bbl (US)/s] is a unit of volumetric flow rate used in the oil and gas industry to measure the volume of crude oil or petroleum products passing through a system every second. One US barrel equals approximately 159 liters, so bbl (US)/s quantifies the number of barrels flowing per second, making it suitable for high-volume, large-scale operations. This unit is commonly applied in pipelines, refineries, and emergency release systems where rapid, continuous monitoring of oil flow is essential. For example, a pipeline delivering 2 bbl (US)/s transports two barrels of crude oil every second, allowing engineers to manage system capacity, prevent overloads, and ensure operational safety. It is also used in industrial processes to regulate crude input for high-speed refining and chemical processing. Compared to bbl (US)/min, bbl (US)/h, or bbl (US)/d, barrel per second provides real-time, high-resolution data, enabling immediate adjustments and precise control of massive fluid flows. Using bbl (US)/s allows oil and energy professionals to monitor, manage, and optimize high-volume crude transport, ensuring efficiency, reliability, and safety in critical energy infrastructure and industrial applications.
