Range of Reynold’s number for the laminar flow of a liquid isa)2...
Reynolds number is a dimensionless quantity that is used to determine the flow characteristics of a fluid. It is defined as the ratio of inertial forces to viscous forces and is given by the formula:
Re = (ρ * v * L) / μ
where Re is the Reynolds number, ρ is the density of the fluid, v is the velocity of the fluid, L is a characteristic length, and μ is the dynamic viscosity of the fluid.
Laminar flow is a type of fluid flow where the fluid moves smoothly in parallel layers with little to no mixing between them. It occurs at low Reynolds numbers when the viscous forces dominate over the inertial forces.
To determine the range of Reynolds numbers for laminar flow, we need to consider the transition from laminar to turbulent flow. This transition occurs when the inertial forces start to dominate over the viscous forces. The exact Reynolds number at which this transition occurs depends on various factors such as the geometry of the flow, surface roughness, and flow conditions.
In general, for the laminar flow of a liquid, the range of Reynolds numbers is typically considered to be less than 1000. This means that at Reynolds numbers below 1000, the flow will be laminar. As the Reynolds number increases beyond 1000, the flow may transition to turbulent flow.
Therefore, the correct answer to the given question is option 'B', which states that the range of Reynolds number for the laminar flow of a liquid is zero to 1000.
