Questions and Answers

According to the equation of continuity in fluid dynamics, what is the relationship between the velocities at two different cross-sectional areas?

  • $A_1 v_1 = A_2 v_2$ (correct)
  • $A_1 v_1 = A_2 / v_2$
  • $A_1 / v_1 = A_2 v_2$
  • $A_1 / v_1 = A_2 / v_2$

In fluid dynamics, what is the relationship between velocity and radius (r) according to the given information?

  • $v = R^2 r$
  • $v = 4r$
  • $v = r^2$
  • $v^2 = R^2 r$ (correct)

What is the correct expression for the viscous force acting on a pebble dropped in a fluid?

  • $F_v = Mg - VD^2g$
  • $F_v = Mg / U$
  • $F_v = Mg + U$
  • $F_v = Mg - U$ (correct)
