Day [gal (UK)/d]

Gallon per day (UK) [gal (UK)/d] is a unit of volumetric flow rate that measures the volume of liquid passing through a system over a 24-hour period, using the UK (Imperial) gallon as the standard. One UK gallon equals approximately 4.546 liters, so gal (UK)/d quantifies daily fluid usage or delivery in this conventional unit. This unit is commonly used in water supply management, agriculture, wastewater treatment, and industrial applications in countries using the Imperial system. For example, municipal water authorities may track household or industrial water consumption in gal (UK)/d to plan distribution, treatment, and storage efficiently. In agriculture, irrigation systems can be designed based on the daily water requirements of crops expressed in UK gallons per day. In industrial processes, monitoring daily liquid usage or discharge in gal (UK)/d helps optimize resource allocation and operational efficiency. Compared to gal (UK)/h or gal (UK)/min, this unit provides a long-term perspective, useful for planning and monitoring overall daily water or fluid consumption. Using gallons per day allows professionals to manage, conserve, and optimize fluid resources, ensuring sustainable, reliable, and efficient operation across residential, agricultural, and industrial contexts.

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.
