Properties Of Solids And Liquids Question 207
Question: In which one of the following cases will the liquid flow in a pipe be most streamlined[Pb. CET 2005]
Options:
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
Show Answer
Answer:
Correct Answer: B
Solution:
For streamline flow, Reynold’s number $ N _{R}\propto \frac{r\rho }{\eta } $ should be less.
For less value of $ N _{R} $ , radius and density should be small and viscosity should be high.
