C = (f*Le)/m

What is dynamic pressure loss and its causes?

The pressure loss due to the change of direction of velocity at the elbow is expressed either in terms of velocity pressure head or equivalent additional length which will give frictional loss equal to that caused by the elbow called Dynamic Pressure loss. The dynamic losses are caused due to the change in direction or magnitude of the velocity of the fluid in the duct. The change in the direction of velocity occurs at bends and elbows. The change in the magnitude of velocity occurs when the area of the duct changes. The change in velocity magnitude or direction can be caused only by the accelerating or decelerating forces which may be internal or external.
