liquid flows into the pipe from the larger area. As shown in Figure-4, the k-values for entrance losses range from 0.04-0.8. Upon exiting a pipe the velocity is assumed to go down to zero which makes the loss equal to the velocity head. This total loss makes the k-value equal to 1 in all cases and is also displayed in Figure-4.
