Entrance loss (He)

The entrance loss (He) is expressed as:

                          (Eq 7.3)

The entrance loss coefficient Ke depends on the inlet geometry due to its effect on the contraction of the flow.

Their values are determined from experiment and are given in Design Chart 27.2 (MSMA,2000) or Design Table 18.A1 (MSMA,2011).
