engineering recuitment Vizag Steel MT Mechanical 2020 Test Series Heat Transfer Convection Dimensionless Numbers
Given that Nu = Nusselt number, Re = Reynolds number, Pr = Prandtl number, Sh = Sherwood number, Sc = Schmidt number and Gr = Grashoff number. The number relationship for free convective heat transfer is given as,
1
Nu = f(Gr, Pr)
2
Sh = f(Sc, Gr)
3
Nu = f(Re, Pr)
4
Sh = f(Re, Sc)
