Non -viscous flow can be a streamline....

Non -viscous flow can be a streamline.

Text Solution

Verified by Experts

The correct Answer is:
False .For non -viscous fluid `eta=0`
`therefore` From `R_(e)=(rhovD)/(eta),R_(e)` = infinite
Hence , such type of flow can never be a streamline.

What is viscous force ?

A non-viscous liquid of constant density 1000kg//m^3 flows in a streamline motion along a tube of variable cross section. The tube is kept inclined in the vertical plane as shown in Figure. The area of cross section of the tube two point P and Q at heights of 2 metres and 5 metres are respectively 4xx10^-3m^2 and 8xx10^-3m^2 . The velocity of the liquid at point P is 1m//s . Find the work done per unit volume by the pressure and the gravity forces as the fluid flows from point P to Q.

What is the effect on velocity of fluid if streamlines are closely spaced ?

A non viscous liquid of constant density 10^(3) kg//m^(3) flows in stream line motion along a vertical tube PQ of variable cross-section. Height of P and Q are 2m and 2.5m respectively. Area of tube at Q is equal to 3 times the area of tube at 'P'. Then work done per unit volume by pressure as liquid flows from P and Q. Speed of liquid at 'P' is 3 m//s .
