What is the term KL in the giver equation of Nusselt number for nucleate boiling heat transfer correlations?

Nub = \(\frac{(\frac{q}{A})D_b}{(T_s-T_{sat})k_L}\)

Thermal conductivity of the vapour

Thermal conductivity of the liquid

Thermal conductivity of the film

Thermal conductivity of the Bubble

The heat flux Q/A depends on the specific heat of the liquid Cf as which one of the following given?

Q/A= δf hfg [(pf – pg) g/σ]0.55 [Cf dt/hfg p] 3

Q/A = δf hfg [(pf – pg) g/σ]0.6 [Cf dt/hfg p Csf]3

Q/A = δf hfg [(pf – pg) g/σ]0.5 [Cf dt/hfg p Csf]3

Q/A = δf hfg [(pf – pg) g/σ]0.5 [Cf dt/hfg p Csf]
