In which one of the following cases will the liquid flow in a pipe be most streamlined?
A
Liquid of high viscosity and high density flowing through a pipe of small radius
B
Liquid of high viscosity and low density flowing through a pipe of small radius
C
Liquid of low viscosity and low density flowing through a pipe of large radius
D
Liquid of low viscosity and high density flowing through a pipe of large radius
Open in App Solution
The correct option is B Liquid of high viscosity and low density flowing through a pipe of small radius
For streamline flow, Reynold's number
N R ∝ r ρ η
should be less. For less value of
N R
, radius and density should be small and viscosity should be high.
