Nusselt number for a pipe flow heat transfer coefficient is given by ...
Explanation:
Nusselt number (Nu) is a dimensionless number that represents the ratio of convective to conductive heat transfer. It is used to determine the heat transfer coefficient for a fluid flowing over a surface. The Nusselt number for a pipe flow heat transfer coefficient is given by the equation NuD = 4.36.
The conditions that apply for use of this value are:
Laminar or Turbulent Flow:
The Nusselt number equation for pipe flow is valid for both laminar and turbulent flow regimes. However, the value of the Nusselt number will be different for laminar and turbulent flows.
Constant Wall Temperature or Constant Wall Heat Flux:
The Nusselt number equation for pipe flow is valid for both constant wall temperature and constant wall heat flux conditions. However, the value of the Nusselt number will be different for constant wall temperature and constant wall heat flux conditions.
Answer:
Option D is the correct answer, which states that the conditions for use of the given Nusselt number value are laminar flow and constant wall heat flux. This means that the fluid flow in the pipe is laminar, and the heat flux at the wall is constant.
