There are three types of flow studied in fluid mechanics.

• Laminar flow

• Turbulent flow

• Transitional flow

An orifice is a small opening or hole through which fluid or gas can flow.

• Orifices are commonly used in various applications such as in pipes, nozzles, and valves.

• They are used to control the flow rate of fluids or gases.

• The size and shape of the orifice determine the flow characteristics.

• Orifices can be circular, rectangular, or any other shape depending on the application.

• Examples of orifices include the nozzle of a ...read more

Steady flow refers to the continuous flow of a fluid without any changes in its properties or characteristics.

• Steady flow occurs when the fluid properties such as velocity, pressure, and temperature remain constant at any given point in the flow field over time.

• In steady flow, the flow rate of the fluid remains constant.

• Examples of steady flow include the flow of water through a pipe with a constant pressure difference...read more
