The flow of fluid at low pressure is said to be

Correct answer: D. Both A and C

  • A. Laminar flow
  • B. Turbulent flow
  • C. Streamline flow
  • D. Both A and C

Explanation

Laminar flow and streamline flow represent the same type of smooth, orderly movement of a fluid. At low pressure (and low velocity), the fluid particles move in parallel layers without mixing. This type of steady, predictable flow is called laminar flow, and when each particle follows a fixed path, it is also called streamline flow. Since both terms describe the same smooth flow condition that occurs at low pressure, both A and C are correct, making option D the right choice.

About Fluid Dynamics

Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
