jH factor for heat transfer is not a function of the __________ number.
A)Reynolds
B)Nusselt
C)Grashoff
D)Both (B) & (C)

Question

Quizplus · Accepted Answer

The jH factor for heat transfer is a dimensionless group used in the correlation of convective heat transfer data. It is not directly a function of the Nusselt number or the Grashoff number. The Nusselt number itself is a dimensionless representation of the convective heat transfer relative to conductive heat transfer across a boundary, while the Grashoff number is a dimensionless number that estimates the ratio of buoyancy to viscous forces in free convection. The jH factor is more directly related to the Reynolds number, which represents the ratio of inertial forces to viscous forces in a fluid flow, affecting the heat transfer characteristics.
