Most modern meters combine a venturi flow rate meter, with a gamma densitometer, and some meters have additional measurements for water salinity. The meter measures the flow rates at line pressures, which are typically orders of magnitude greater than atmospheric pressure, but the meter must report the oil and gas volumes at standard ...
A thermal mass flow meter has a turndown ratio of 1000:1. An orifice plate meter has a practical turndown ratio of 3:1. A turbine meter has a turndown ratio of 10:1. Rotary positive displacement meters have a turndown ratio of between 10:1 and 80:1, depending on the manufacturer and the application.
Each load uses on average 29.3 gallons (111 liters) of water. According to EPA, a full-sized Energy Star certified clothes washer (with "water factor" - WF ≤ 8.0 gal/cycle/ft^3) should use on average 15 gallons (57 liters) of water per load, compared to at least two times that volume used by a standard machine.

These consist chiefly of soils with a layer that impedes downward movement of water or soils with moderately fine to fine textures. These soils have a slow rate of water transmission (final infiltration rate 0.05–0.15 in (1.3–3.8 mm) per hour). HSG Group D (high runoff potential): Soils with very slow infiltration rates when thoroughly ...
Municipal volumetric water measurements, including city water flow and cost per unit on a residential water bill, can either be measured in gallons, cubic feet, or cubic meters, with gallons being the most commonly used. Water bottles for personal use can have their capacity measured in fluid ounces or liters. For ounces, the measurements are ...
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of ...
Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
US dry barrel: 7,056 cubic inches (115.6 litres; 3.3 US bushels) . Defined as length of stave 28 + 1 ⁄ 2 in (72 cm), diameter of head 17 + 1 ⁄ 8 in (43 cm), distance between heads 26 in (66 cm), circumference of bulge 64 in (160 cm) outside measurement; representing as nearly as possible 7,056 cubic inches; and the thickness of staves not greater than 4 ⁄ 10 in (10 mm) [2] (diameter ≈ ...
