In a forced vortex motion, the velocity of flow is A. directly proportional to its radial distance from axis of rotation B. inversely proportional to its radial distance from the axis of rotation C. inversely proportional to the square of its radial distance from the axis of rotation D. directly proportional to the square of its radial distance from the axis of rotation

The correct answer is: A. directly proportional to its radial distance from axis of rotation.

A forced vortex is a type of fluid flow in which the velocity of the fluid is directly proportional to its radial distance from the axis of rotation. This means that the faster the fluid is moving,

The other options are incorrect because they do not accurately describe the velocity of flow in a forced vortex. Option B states that the velocity of flow is inversely proportional to its radial distance from the axis of rotation. This means that the faster the fluid is moving, the closer it is to the axis of rotation. This is not the case in a forced vortex, where the velocity of flow is directly proportional to the radial distance from the axis of rotation. Option C states that the velocity of flow is inversely proportional to the square of its radial distance from the axis of rotation. This means that the faster the fluid is moving, the closer it is to the axis of rotation squared. This is also not the case in a forced vortex, where the velocity of flow is directly proportional to the radial distance from the axis of rotation. Option D states that the velocity of flow is directly proportional to the square of its radial distance from the axis of rotation. This means that the faster the fluid is moving, the further it is from the axis of rotation squared. This is also not the case in a forced vortex, where the velocity of flow is directly
