contraction loss

[kən′trak·shən ‚lȯs]
(fluid mechanics)
In fluid flow, the loss in mechanical energy in a stream flowing through a closed duct or pipe when there is a sudden contraction of the cross-sectional area of the passage.

The approach will be to relate the contraction loss, as flow goes from the access hole into the outflow pipe, to the contracted area (vena contracta) in the outflow pipe.
If the vena contracta is an indirect measure of the contraction loss for the outflow pipe, it would lead to an indirect measure of the total energy in the access hole, regardless of the inflow pipe configuration.
