This number can be used to determine the thermal conductivity of gases at high temperature and it also delivers us the information about the thickness of thermal and hydrodynamic boundary layer.

2.5 Reynolds Number
In fluid mechanics, the dimensionless quantity, fraction of inertial forces to viscous forces, is known as Reynolds Number.
Reynolds number can be shown as ,

Newton’s law of viscosity discussed above is designed for the one dimensional fluid flow.
2.9 Types of Fluid
Some types of fluid are given below
2.9.1 Newtonian Fluid
Newtonian fluids are labeled after Isaac Newton, who first proposed the relation between the shear strain rate and the shear stress for fluids in differential form. Real fluids in which the viscous stresses are arising from the flow, at every point, are linearly proportional to the local strain rate (the rate of change of deformation over time) are known as Newtonian fluid. In these fluids shear force or tensile stress is not symmetric and nor proportional to rate of deformation. The viscosity of the Newtonian fluid is always temperature dependent.
Examples
Water, Glycerin, Milk and Petroleum are few examples of the Newtonian fluid.
2.9.2 Non-Newtonian Fluid
Non-Newtonian fluid is the fluid which does not follow the Newton’s law of …show more content…

The reaction of the metals with acids, the electrochemical fluctuations that happen in batteries and electrolytic cells, and the phenomena of corrosion are part of the focus of the heterogeneous reactions.
2.14 Finite Difference Approximations to Derivatives
Finite difference scheme can be categorized and formulated in Taylor series expansions. When a function and its derivatives are single valued, finite and the continuous functions then the Taylor series expansion for function may be written at particular point as: (2.14.1) (2.14.2)
By reordering above mentioned terms, we may
