Hour [gal (UK)/h]

Gallon per hour (UK) [gal (UK)/h] is a unit of volumetric flow rate that measures the volume of liquid passing through a system every hour, using the UK (Imperial) gallon as the standard. One UK gallon equals approximately 4.546 liters, so gal (UK)/h quantifies the amount of fluid flowing in a sixty-minute period. This unit is commonly used in industrial processes, water distribution, chemical dosing, and agricultural irrigation in regions where the Imperial gallon is standard. For example, in water treatment plants, pumping stations are often rated in gal (UK)/h to ensure that the correct volume of water is delivered or treated each hour. In agriculture, irrigation systems may rely on gal (UK)/h to regulate water supply to crops efficiently. In industrial chemical processes, this unit helps control the flow of liquids for precise reactions, manufacturing, or production requirements. Compared to gal (UK)/d, gallon per hour provides finer temporal resolution, allowing more frequent monitoring and real-time adjustments. Using gal (UK)/h enables engineers, technicians, and managers to measure, regulate, and optimize fluid flow, ensuring efficiency, reliability, and proper resource management in various 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.
