Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

For kinematic viscosity, the SI unit is m^2/s. In engineering, the unit is usually Stoke or centiStoke, with 1 Stoke = 0.0001 m^2/s, and 1 centiStoke = 0.01 Stoke. For liquid, the dynamic viscosity is usually in the range of 0.001 to 1 Pascal-second, or 1 to 1000 centiPoise. The density is usually on the order of 1000 kg/m^3, i.e. that of water.
Depending on the solute and range of concentration, an aqueous electrolyte solution can have either a larger or smaller viscosity compared with pure water at the same temperature and pressure. For instance, a 20% saline ( sodium chloride ) solution has viscosity over 1.5 times that of pure water, whereas a 20% potassium iodide solution has ...
The gas viscosity model of Chung et alios (1988) [5] is combination of the Chapman–Enskog(1964) kinetic theory of viscosity for dilute gases and the empirical expression of Neufeld et alios (1972) [6] for the reduced collision integral, but expanded empirical to handle polyatomic, polar and hydrogen bonding fluids over a wide temperature ...

Increasing temperature results in a decrease in viscosity because a larger temperature means particles have greater thermal energy and are more easily able to overcome the attractive forces binding them together. An everyday example of this viscosity decrease is cooking oil moving more fluidly in a hot frying pan than in a cold one.
The coefficient typically ranges from about (for strong solvents) to (for poor solvents). [ 3 ] The Huggins equation is a useful tool because it can be used to determine the intrinsic viscosity, [ η ] {\displaystyle [\eta ]} , from experimental data by plotting η s c {\displaystyle {\frac {\eta _{s}}{c}}} versus the concentration of the ...
