Cubic Yard/Hour [yd³/h]

Cubic yard per hour [yd³/h] is a unit of volumetric flow rate that measures the volume of material or fluid passing through a system every hour, based on the cubic yard. One cubic yard equals 27 cubic feet or approximately 0.7646 cubic meters. When expressed per hour, yd³/h quantifies the flow of solids, liquids, or slurries in industrial, construction, or agricultural applications. For example, in concrete production, a plant may produce 50 yd³/h of concrete, allowing contractors to plan pours and manage delivery schedules efficiently. In mining or bulk material handling, conveyor systems are often rated in yd³/h to ensure materials are transported at the required rate without bottlenecks. Compared to yd³/day, this unit provides finer temporal resolution, enabling operators to monitor and adjust flow in near real-time. It is also used in wastewater treatment, irrigation, and dredging operations where managing large volumes accurately is essential. Using cubic yards per hour allows engineers, operators, and planners to measure, regulate, and optimize volumetric flow, ensuring efficiency, safety, and reliability in construction, industrial, and water resource 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.
