Centimeter/Hour [cm³/h]

Cubic centimeter per hour (cm³/h) is a unit of volumetric flow rate that measures the volume of a fluid—liquid or gas—moving through a system over one hour. One cubic centimeter is the volume of a cube with sides of one centimeter, so cm³/h quantifies how many such small volumes flow every hour. This unit is widely used in laboratory experiments, medical infusions, chemical dosing, and precision fluid systems where very low flow rates must be accurately controlled. For example, in medical applications, intravenous medication or nutrient delivery is often regulated in cm³/h to ensure patients receive the exact required dose over time. In chemical or analytical laboratories, pumps dispensing reagents rely on cm³/h measurements for accurate reactions and experiments. Compared to cm³/d, this unit provides finer resolution for processes that require monitoring on an hourly basis, making it ideal for controlled, slow, and continuous flows. Using cubic centimeters per hour allows scientists, engineers, and technicians to measure, manage, and optimize fluid delivery with high precision, ensuring accuracy, safety, and consistency in applications where small variations can significantly affect results.

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.
