Cubic Foot/Hour [ft³/h]

Cubic foot per hour [ft³/h] is a unit of volumetric flow rate that measures the volume of fluid or material passing through a system every hour, based on the cubic foot. One cubic foot equals approximately 28.3168 liters. When expressed per hour, ft³/h is commonly used in industrial processes, HVAC systems, water supply, and small-scale fluid handling where moderate flow rates need to be monitored and controlled. For example, in a water treatment plant, a pump delivering 50 ft³/h ensures the required volume of water is processed efficiently over time. In HVAC systems, ft³/h helps quantify airflow through ducts to maintain proper ventilation and indoor air quality. It is also used in laboratories and small industrial applications to measure chemical solutions or bulk materials transported by conveyors. Compared to ft³/day, cubic foot per hour provides finer temporal resolution, enabling operators to monitor and adjust flow rates more effectively. Using cubic feet per hour allows engineers, technicians, and facility managers to measure, regulate, and optimize volumetric flow, ensuring operational efficiency, safety, and reliability in industrial, municipal, and laboratory applications.

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.
