Reynolds number is replaced by a modulus significant of the agitation of the fluid particles in nucleate boiling. Such a dimensionless modulus is defined by the relation

A. Re <sub>b </sub>= 2 D <sub>b </sub>G <sub>b</sub>/ <sub>f</sub>
B. Re <sub>b </sub>= D <sub>b </sub>G <sub>b</sub>/ <sub>f</sub>
C. Re <sub>b </sub>= D <sub>b </sub>G <sub>b</sub>/ <sub>f</sub>
D. Re <sub>b </sub>= 3 D <sub>b </sub>G <sub>b</sub>/ <sub>f</sub><sup></sup>
Answer» C. Re <sub>b </sub>= D <sub>b </sub>G <sub>b</sub>/ <sub>f</sub>
