Test: Kinematics of Flow & Ideal Flow - 2 - Mechanical Engineering MCQ

radial streamlines

zero circulation around it

rotational fluid at ail radii

constant circulation around a closed path including the origi

a source flow represents a singular point source of spontaneous mass creation

the path of fluid particles is purely radial

the strength of source is defined as the volume flow rate per unit depth per unit time.

the streamlines are the concentric circles and the- equipotential lines are the radial lines from the source

the source and sink are of equal- strength .

the source strength exceeds the sink strength

the source and sink coincide while moving along the axis

the source-sink pair of equal strength approach each other such that the product of strength and the distance remains constan
