Actual velocity of jet at vena contracta to the theoretical velocity
Defining the Coefficient of Velocity (C_v) The coefficient of velocity (C_v) is a dimensionless quantity that represents the ratio of the actual velocity of the fluid jet at the vena contracta to the theoretical velocity that would be achieved under ideal conditions (without considering losses like friction and viscosity). Actual velocity of jet at vena contracta to the theoretical velocity This option precisely matches the definition of the coefficient of velocity (C_v) as established in fluid mechanics.
