## Boundary layer thickness of laminar sublayer Solution

STEP 0: Pre-Calculation Summary
Formula Used
boundary_layer_thickness = (11.6*Kinematic viscosity)/(Shear Velocity)
δ = (11.6*ν)/(V*)
This formula uses 2 Variables
Variables Used
Kinematic viscosity - The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid. (Measured in Stokes)
Shear Velocity - Shear velocity, also called friction velocity, is a form by which a shear stress may be re-written in units of velocity. (Measured in Meter per Second)
STEP 1: Convert Input(s) to Base Unit
Kinematic viscosity: 7.25 Stokes --> 0.000725 Meter² per Second (Check conversion here)
Shear Velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
δ = (11.6*ν)/(V*) --> (11.6*0.000725)/(10)
Evaluating ... ...
δ = 0.000841
STEP 3: Convert Result to Output's Unit
0.000841 Meter --> No Conversion Required
0.000841 Meter <-- Boundary layer thickness

## How is boundary layer thickness defined?

We define the thickness of the boundary layer as the distance from the wall to the point where the velocity is 99% of the “free stream” velocity.

## What affects thickness of boundary layer?

The thermal boundary layer thickness is altered due to the presence of flow during boiling in microchannels. If the flow rates are high, the thermal boundary layer thickness is reduced.
