It is the ratio of the area of the jet at venacontracta to the area of orifice,
Cc = Area at vena contracta/ Area of orifice
The typical value may be taken as 0.64 for a sharp orifice (concentric with the flow channel). The smaller the value, the more effect the vena contracta has.

Vena means diameter and contracta means reduction. So, vena contracta means reduced diameter where the velocity of flow is maximum.

Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum.

Vanacontracta is minimum diameter of fluid which is just outflow from any container or orifice hole.

Orifice is a very small hole through which fluid is allowed to flow.
