Reynolds number signifies the ratio of ____________(a) inertia forces

1.	Reynolds number signifies the ratio of ____________(a) inertia forces to gravity forces(b) buoyant forces to inertia forces(c) inertial forces to viscous forces(d) gravity forces top viscous forcesThe question was posed to me in an interview for job.The origin of the question is Fluids in Motion in portion Fluid Flow and Mixing of Bioprocess Engineering
Answer» Correct option is (c) inertial forces to VISCOUS forces For explanation: The Reynolds number is the ratio of inertial forces to viscous forces WITHIN a fluid which is subjected to relative internal movement due to different fluid velocities, in which is KNOWN as a boundary layer in the case of a BOUNDING SURFACE such as the interior of a pipe.
