flow process : it is one in which fluid enters the system and leaves it after work interaction,which means that such processes occur in the systems having open boundary permitting mass interaction across the system boundary.
non flow process : it is the one in which there is no mass interaction across the system boundaries during the occurrence of process.
different type of non flow process of perfect gas are given below:
(1) constant volume process
(2) constant pressure process
(3) Isothermal process
(4) adiabatic process
(5) polytropic process

Steady flow: laminar flow over a sphere. Unsteady flow: turbulent flow over anything.

Non-positive displacement has slippage inside the pump and it is a continous, variable flow. But positive displacement has no slippage inside the pump, and it is a constant flow.
it mean that it can not be compressed
Flow process takes place in open system & non-flow process takes place in closed system.
Flow through the OPen systems called Flow Process Flow through the Closed systems called NON Flow process.

Steady flow processFluid flow in which all the conditions at any one point are constant with respect to timeFluid flow without any change in composition or phase equilibriaFlow velocities do not vary with timeExamples of steady flow process- groundwater and channel flows- turbine- fluid heater- orifice(throttling)- nozzleNon flow processA thermodynamic process involving no fluid flowExamples of non-flow process- Heating at constant volume- Adiabatic expansion in a cylinder- Free Expansion (Joules experiment - valve is initially closed and then opened to equalize pressures)- Heating a fluid in a cylinder at constant pressure
A process flow sheet or diagram is used to show the flow of plant processes and equipment. Process flow sheets of multiple process units are called block or schematic flow diagrams.

what is steady state flow process in fluid dynamics
Flow chart: - A flow chart is a symbolic representation of any process. Each step in the process is represented by a different symbol with a short description of the process. The flow chart symbols are linked together with arrows showing the process flow direction.There ate two types of flow charts1. Low level flow chart2. High level flow chart
information flow and process flow
Flow is Laminar.
