When a liquid rotates at a constant angular velocity about a vertical axis as a rigid body, the pressure intensity varies as the square of the radial distance inversely as the radial distance inversely as the square of the radial distance linearly with radial distance TRUE ANSWER : ? YOUR ANSWER : ?
Steady flow occurs when the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time the magnitude and direction of the velocity do not change from point to point in the fluid the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane the direction and magnitude of the velocity at all points are identical TRUE ANSWER : ?
