Refugees and asylum seekers in Lebanon make up about 10 percent of the country's total population. Palestinians make up the majority of refugees, followed by Kurds, Iraqis, and Sudanese (see Table 1).
The resistance of gas or liquid to flow? The resistance of a liquid to flowing is its viscosity.   Viscosity is a property arising from friction between  neighboring particles in a fluid that are moving at difâ¦ferent  velocities. In liquids, it could be considered the thickness.
However, when frictional effects are small, a flow may be approximately reversible. For instance, in the flow through a large duct where the boundary layers are very thin, viscous effects are confined to a rather small region, and the fluid friction may sometimes be neglected. This is not the case for most practical flows.
