Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow occurs at lower
disturbances are damped out by the fluid viscosity and the flow remains laminar, but at high Re (when convective momentum transport dominates over viscous forces) they can grow and propagate, giving rise to the chaotic phenomena perceived as turbulence. Turbulent flows can be very difficult to analyze.

The ratio of molecular mass transport resistance to the convective mass transport resistance of the fluid. This ratio is generally known as the Sherwood number, Sh and analogous to the Nusselt number Nu, in heat transfer.
The rate of convection heat transfer is expressed by Newton’s law of cooling: Q hA T T W q h T T W m conv s conv s / 2 The convective heat transfer coefficient h strongly depends on the fluid properties and roughness of the solid surface, and the type of the fluid flow (laminar or turbulent).
Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow occurs at lower

disturbances are damped out by the fluid viscosity and the flow remains laminar, but at high Re (when convective momentum transport dominates over viscous forces) they can grow and propagate, giving rise to the chaotic phenomena perceived as turbulence. Turbulent flows can be very difficult to analyze.
Thus, the Peclet number tells us the relative importance of convective transport of thermal energy when compared with molecular transport of thermal energy (conduction). The Sieder-Tate correlation is useful only for relatively short tubes. A heat transfer correlation for laminar flow that applies regardless of the tube length, given in Mills
1.1.1 Turbulent and laminar flow in pipes The flow in conventional control valve installations is almost always turbulent. Laminar flow can occur with very viscous fluids such as lube oil and with very small flow velocities.
