Dutch term or phrase: tophoek

Bij convergerende kanaalstukken moeten scherpe hoeken en kanten vermeden worden; de tophoek mag 120 grd. bedragen

Bij diffusoren mag de tophoek maximaal 10 graden bedragen.

Is this the angle from the perpendicular?

thanks!

17 hrs confidence:

convergence angle (first mention); divergence angle (second mention)

Explanation:
The angle between two converging or diverging ducts which are both connected to a third duct. If the two ducts are feeding the third duct it is an angle of convergence. If the two ducts are fed by the third duct it is an angle of divergence (diffuser situation). When the feeding or fed duct is vertical the angle of convergence or divergence will be <on top> of the Y shape thus formed, thus <tophoek>.
Note: There are various applications of <tophoek>/top angle/vertex angle (not all of them established or consistent) in geometry, in relation to intersecting lines, polygons and (isosceles) triangles, but these do not seem applicable here and, in at least one meaning of vertex, an angle of 120º, as mentioned in the text, would be impossible - though eminently possible in the case of converging/diverging ducts.

Example sentence(s):

From 1st ref., below: ... [in] convergent and divergent ducts ... the Nusselt number increases with increasing convergent/divergent angles ...
From 2nd ref., below: Because of the irregular angle of convergence, angle of divergence and the irregular cross-sectional area of the duct, the cool air is not evenly distributed...
