Reynold’s number (r), a dimensionless quantity determines the condition for laminar flow of a viscous liquid through a pipe. r is a function of density p of the liquid, its speed of flow v and coefficient of viscosity n . r is directly proportional to diameter d of the tube through which it flows. show that r is proportional to pvd/n

truck y has a greater velocity than truck x.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
