In vortex fluid flow velocity is ______________ to the distance from the axis line.
A. directly proportional
B. inversely proportional
C. not related
D. none
Answer:A
In vortex fluid flow velocity is ______________ to the distance from the axis line.
A. directly proportional B. inversely proportional C. not related D. none
Explanation: In vortex fluid velocity is more near to the axis and decreases as the distance from the axis line increases. Hence Fluid flow velocity is inversely proportional to the distance from the axis line.
