All the flow patterns we deal with are mostly plug flow and mixed flow. But in real scenario there is a deviation from this behavior. This is called a non ideal flow.
3 interrelated factors that makeup the contacting or flow pattern are:
1) RTD, or residence time distribution
2) state of aggregation (flowing materials tendency to clump and for a group of molecules to move about together)
3) earliness and lateness of mixing of material in the vessel.
Two types of non-ideal solutions are ideal mixtures and non-ideal mixtures. Ideal mixtures follow Raoult's Law, where the vapor pressure of each component is directly proportional to its mole fraction in the solution. Non-ideal mixtures do not obey Raoult's Law due to interactions between the components, such as deviations from ideal behavior or the formation of new chemical species.
Viscosity denotes opposition to flow.
Flow nets are used to visualize and analyze flow patterns in 2D problems with steady-state and incompressible flow. They help in understanding the velocity and pressure distribution within a domain. However, flow nets are limited in that they do not provide information about 3D flow behavior, transient flow phenomena, or turbulence effects. Additionally, they are not typically used for complex geometries or non-ideal fluid behaviors.
The gas molecules interact with one another
An example of something with low viscosity, like water, would be a non-example of viscosity. Viscosity refers to the resistance of a fluid to flow, so a non-example would be any substance that does not resist flow, such as gases.
Uniform flow is a characteristic of ideal fluid behavior, where the fluid moves in a steady and consistent manner without any disturbances or variations in flow velocity or pressure. Ideal fluid assumes that the flow is frictionless, incompressible, and irrotational, which allows for the simplification of fluid dynamics equations. However, in reality, ideal fluids do not exist, and all real fluids exhibit some level of viscosity and other non-ideal behaviors.
They are two types of Non-Ideal solutions. They are (i) Non-Ideal solutions showing positive deviation (ii) Non-ideal solutions showing negative deviation
Two types of non-ideal solutions are ideal mixtures and non-ideal mixtures. Ideal mixtures follow Raoult's Law, where the vapor pressure of each component is directly proportional to its mole fraction in the solution. Non-ideal mixtures do not obey Raoult's Law due to interactions between the components, such as deviations from ideal behavior or the formation of new chemical species.

Flow through the OPen systems called Flow Process Flow through the Closed systems called NON Flow process.
Flow process takes place in open system & non-flow process takes place in closed system.
Viscosity denotes opposition to flow.
Uniform flow occurs when the fluid velocity and properties are constant throughout the flow field, while non-uniform flow has varying velocity and properties across the flow field. In uniform flow, streamlines are parallel and the flow is steady, whereas in non-uniform flow, streamlines may converge or diverge and the flow can be unsteady.
Steady flow: Water flowing through a pipe at a constant rate with uniform velocity is an example of steady flow. Non-steady flow: Waves in the ocean where the water motion is constantly changing in both intensity and direction represent non-steady flow.
The mass flow rate is the amount of mass passing through a given point per unit of time. In the ideal gas law, the mass of the gas is not a factor, as it only considers the pressure, volume, and temperature of the gas. Therefore, the mass flow rate does not directly affect the ideal gas law.
