Steady flow:- The flow is said to be steady when the flow characteristics, such as velocity, pressure, density and temperature do not change with time.
Water flowing through a tap at a constant rate is an example of steady flow.
Uniform flow:- The flow in which velocity at a given time does not change with respect to space (length of direction of flow) is called as uniform flow. This term is generally applied to flow in channels.
Laminar flow:- The flow in which each liquid particle has definite path and path of individual particles do not cross each other is called as laminar flow. e.g. Movement of blood in human body, the flow of thick oil through a small tube.
Turbulent flow:- Flow in which each liquid particle does not have a definite path and the path of individual particles also cross each other is called as turbulent flow.
e.g. The flow of river at the time of flood is turbulent flow.
