Relation between Velocity Coefficient & Nozzle efficiency

Q.  What is the relation between Velocity Coefficient (Cc) and Nozzle efficiency (ηn)?
- Published on 16 Sep 15

a. Cc = (1/2) (ηn)
b. Cc = √(ηn)
c. Cc = (ηn)2
d. Cc = (ηn)3

ANSWER: Cc = √(ηn)

    The Velocity Coefficient (Cc) can be defined as the ratio of actual exit velocity to the ideal exit velocity.


    Cc = (Actual exit velocity) / (Ideal exit velocity)

    Cc = √((Actual enthalpy drop) / (Ideal enthalpy drop))

    Cc = √(Nozzle Efficiency)

    Cc = √(ηn)
