Streamline flow is more likely for liquids with

a) high density

b) high viscosity

c) low density

d) low viscosity

Answers (1)

The answer is the option (b) and (c)

Liquids which have a lesser density are more subjected to a streamline flow. The velocity gradient of liquid increases with its viscosity. Hence the line of flows can be differentiated accordingly.

Reynold number, R =\frac{ pvD}{n}

As we increase n and decrease p, R decreases. This decrease in R makes the flow more streamlined. Hence options b and c are correct.
