We know that JH =Nst x (Npr)2/3= f/2, So JH is depended upon Npr.

@RAMESH. That Jh is heat flux but in question, Jh mentioned is the friction correction factor for calculating pressure drop.

Jh = Nu/Re.Pr^1/3.
So, jh will depend on Nu, Re & pr.

Jh factor can be written as below [(Re^0.8) * (pr^0.3) * (pr^0.6)]/(Re * pr) = Re^-0.2.
So, jh factor depends on only re.
