Q. What is D’Alembert’s Paradox?

  • (A) resistance= 0
  • (B) drag force= 0
  • (C) temperature = 0
  • (D) pressure gradient= 0
💬 Discuss
✅ Correct Answer: (B) drag force= 0
Explanation: d’alembert’s paradox states that for an incompressible and inviscid flow potential flow, the drag force is equal to zero. the fluid is moving at a constant velocity with respect to its relative fluid.
