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.


Hundred-Cubic Foot/Hour [hcf/h]


Hundred-cubic foot per hour [hcf/h] is a unit of volumetric flow rate commonly used in municipal water supply, industrial processes, and fluid management systems. One hundred cubic feet (hcf) equals 100 cubic feet of water, approximately 2,832 liters or 748 gallons. When expressed per hour, hcf/h measures the volume of water delivered, consumed, or transported in a single 60-minute period. This unit is particularly useful for monitoring medium- to large-scale water flows in real time, such as in water distribution networks, irrigation systems, and industrial cooling processes. For example, a pumping station delivering 10 hcf/h transports 1,000 cubic feet of water per hour, allowing engineers to manage flow rates, prevent shortages, and optimize system performance. It is also applied in industrial operations where precise control of water or fluid flow is critical for process efficiency and safety. Compared to hcf/d, hundred-cubic foot per hour provides short-term, high-resolution monitoring, enabling timely adjustments and operational decisions. Using hcf/h allows water engineers, facility managers, and industrial operators to track, regulate, and optimize water flow, ensuring reliability, efficiency, and effective resource management across municipal and industrial applications.
