LAMINAR_T_CONST
This function returns the theoretical fully developed laminar Nusselt number for internal pipe flow with constant wall temperature. It provides the canonical baseline value for laminar internal-convection calculations under isothermal wall conditions.
Excel Usage
=LAMINAR_T_CONST()Returns (float): Constant wall temperature Nusselt number (-).
