1. Manager 2015 Paper 2 (Civil) · Q71 · Fluid Mechanics & Hydraulics · Fluid Mechanics

   Reynolds number of a flow is the ratio of

   1. Gravity forces to viscous forces
   2. Gravity forces to pressure forces
   3. Inertia forces to viscous forces
   4. Viscous forces to pressure forces
   Show answer

   Answer: (3) Inertia forces to viscous forces

   Re = ρVD/μ = inertia force / viscous force; the ratio involving gravity (inertia to gravity) is the Froude number.
