What is entrance loss?

The entrance loss is the head loss that occurs when a liquid flows from a large tank into a pipe. At the entrance to the pipe, the liquid must accelerate from zero velocity at the liquid surface in the tank to the velocity corresponding to the flow rate through the pipe.

What are the reason for minor head losses in pipe?

Major losses occur due to the friction effect between the moving fluid and the walls of the pipe. The minor losses occur due to any disturbance that might occur to the flow, which is mainly caused by the installed fittings on the pipeline.
