                  Streamline flow is more likely for liquids with                 (a) high density                 (b) high viscosity                 (c) low density                  (d) low viscosity                

Answer:

                  (b, c)                 Critical velocity \[({{\upsilon }_{c}})\] is related to viscosity \[(\eta )\] and density \[(\rho )\] of the liquid as:                 (b) \[{{\upsilon }_{c}}\propto \eta \]                 (c) \[{{\upsilon }_{c}}\propto \frac{1}{\rho }\]
