We often use grams per milliliter (g/mL) or grams per cubic centimeter (g/cm 3) for the densities of solids and liquids. Although there are exceptions, most liquids and solids have densities that range from about 0.7 g/mL (the density of gasoline) to 19 g/mL (the density of gold).
1 Ιαν 2019 · Engineering properties of foods may be defined as the characteristics exhibited by foods and other biological materials under certain form and state of energy.
The specific weight of a substance is the weight per unit volume. Specific weight is usually given the symbol \(\gamma\) ("gamma") and can be calculated as the product of density times the local acceleration of gravity: \[\gamma=\rho g \nonumber \] Any values of specific weight you find listed in a table have, of necessity, assumed a value for ...
The specific weight of a fluid, designated by the Greek symbol (gamma), is defined as its weight per unit volume. Thus, specific weight is related to density
Specific Weight is defined as weight per unit volume . Weight is a force . The SI unit for specific weight is [N/m 3]. The imperial unit is [lb/ft 3]. Specific Weight (or force per unit volume) can be expressed as. γ = ρ a g (4) where γ = specific weight (N/m 3], [lb/ft 3] ρ = density [kg/m 3], [slugs/ft 3]
Specific Gravity - SG - is a dimensionless unit defined for liquids as "the ratio of the density of the substance to the density of water at a specified temperature". For gases the Specific Gravity is related to air. Specific Gravity for common fluids are indicated in the table below.
For accurate calculation of energy balance during heating and cooling process, it is important to know the behavior of thermal data of foods in terms of specific heat, thermal conductivity, and thermal diffusivity. The determinations of different thermal properties are illustrated with diagrams and solved examples. Download chapter PDF.
