Which one of the statements is correct for a forced vortex?

• A. Turns in an opposite direction to a free vortex
• B. Always occurs in conjunction with a free vortex
• C. Has the linear velocity directly proportional to the radius
• D. Has the linear velocity inversely proportional to the radius

Answer 1

Answer:

C. Has the linear velocity directly proportional to the radius

A forced vortex is a rotational flow influenced by an external torque. The linear velocity of the forced vortex is directly proportional to the radius,
