‡ In Canada, a cup was historically 8 imperial fluid ounces (227 mL) but could also refer to 10 imperial fl oz (284 mL), as in Britain, and even a metric cup of 250 mL. Serving sizes on nutrition labelling on food packages in Canada employ the metric cup of 250 mL, with nutrition labelling in the US using a cup of 240 mL, based on the US ...
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
The bulk volume of a material —inclusive of the void space fraction— is often obtained by a simple measurement (e.g. with a calibrated measuring cup) or geometrically from known dimensions. Mass divided by bulk volume determines bulk density. This is not the same thing as the material volumetric mass density.
A measuring cup, a common instrument used to measure volume. Buoyant weight (solids) Eudiometer, pneumatic trough (gases) Flow measurement devices (liquids) Graduated cylinder (liquids) Measuring cup (grained solids, liquids) Overflow trough (solids) Pipette (liquids) If the mass density of a solid is known, weighing allows to calculate the volume.
A simple plastic measuring cup, capable of holding the volume one cup. A measuring cup is a kitchen utensil used primarily to measure the volume of liquid or bulk solid cooking ingredients such as flour and sugar, especially for volumes from about 50 mL (approx. 2 fl oz) upwards. Measuring cups are also used to measure washing powder, liquid ...
V eq is the volume of titrant (ml) consumed by the crude oil sample and 1 ml of spiking solution at the equivalent point, b eq is the volume of titrant (ml) consumed by 1 ml of spiking solution at the equivalent point, 56.1 g/mol is the molecular weight of KOH, W oil is the mass of the sample in grams. The normality (N) of titrant is calculated as:
Dashes, pinches, and smidgens are all traditionally very small amounts well under a teaspoon, but not more uniformly defined. In the early 2000s some companies began selling measuring spoons that defined a dash as 1 ⁄ 8 teaspoon, a pinch as 1 ⁄ 16 teaspoon, and a smidgen as 1 ⁄ 32 teaspoon.
There are commercial tubes for stalagmometric method in three sizes: 2.5, 3.5, and 5.0 (mL). The 2.5-mL size is suitable for small volumes and low viscosity, that of 3.5 (mL) for relatively viscous fluids, and that of 5.0 (mL) for large volumes and high viscosity. The 2.5-mL size is suitable for most fluids. [6]
