What is the speed of an incompressible non-viscous liquid flowing out from 'B' contained in a container as shown in the figure? Where AB = 5 m and g = 10 m/s₂

Correct answer: B. 10m/s

  • A. 5m/s
  • B. 10m/s
  • C. 2m/s
  • D. 50m/s

Explanation

v2=u2+2as→v2 =0+2(5)(10)→v2=100→v= 10 m/s. As it is a numerical, it can have only one possible answer.

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.
