Final answer:

The question pertains to determining the temperature distribution in laminar flow through a tube with a constant wall temperature, which is an engineering and physics problem. It involves applying Poiseuille's Law and solving differential equations for energy and momentum balance in fluid dynamics.

Step-by-step explanation:

The question asks to determine the temperature distribution in the laminar flow of incompressible Newtonian fluid through a tube, assuming that the wall of the tube is maintained at a constant temperature. This problem falls under the category of fluid dynamics, a sub-discipline of Physics and Engineering, particularly thermodynamics and fluid mechanics.

In laminar flow, the fluid moves in layers or laminae, with minimal mixing and disturbance between them. The temperature distribution in such a flow can be determined using principles from Poiseuille's Law, which relates the flow rate of a viscous fluid in a pipe to the other physical properties of the fluid and the pipe. Since the flow is assumed to be laminar and the physical properties are constant, this suggests a stable flow condition without fluctuations in temperature except across the radius of the tube.

When analyzing the temperature profile in a tube, with the assumption of constant wall temperature, one would need to solve a form of the energy balance (derived from the first law of thermodynamics) alongside the momentum balance (Navier-Stokes equations). If we assume a fully developed laminar flow and a constant physical properties scenario, the resulting temperature distribution is typically parabolic across the tube radius, with the highest temperature at the walls and the lowest at the center, assuming the wall temperature is higher than the fluid temperature entering the tube.

To fully determine the temperature distribution, differential equations incorporating the boundary conditions (e.g., constant wall temperature) would need to be solved, which typically requires knowledge of advanced mathematics and thermal fluid sciences common at the college level. The final distribution would be expressed as a function of radial position within the tube, allowing for the temperature at any point to be calculated.

For example, the heat transfer in the tube can be characterized by the conductive and convective processes, and the temperature distribution can be derived assuming a steady-state condition using Fourier's Law of heat conduction in conjunction with convective boundary conditions at the tube surface.
