Reynolds number gives the relative importance of __________(a) viscous

1.	Reynolds number gives the relative importance of __________(a) viscous force and tangential force(b) inertia force and viscous force(c) inertia force and pressure force(d) pressure force and viscous forceThe question was posed to me in final exam.My question comes from Turbulence Modelling in division Turbulence Modelling of Computational Fluid Dynamics
Answer» Right option is (b) INERTIA force and viscous force Easy EXPLANATION: REYNOLDS number DECIDES whether the flow is laminar or TURBULENT. Reynolds number of flow gives the relative importance of inertia force (convective forces) and viscous forces.
