Explanation:

Laminar Flow in a Tube:
In the case of laminar flow in a tube, the flow is smooth and orderly, with fluid moving in parallel layers.

Constant Heat Flux Condition:
Under constant heat flux condition, the heat transfer rate remains constant along the length of the tube.

Nusselt Number:
The Nusselt number (Nu) is a dimensionless number used to determine the heat transfer between a fluid and a solid surface. It is defined as the ratio of convective heat transfer to conductive heat transfer.

Approximate Value of Nusselt Number for Constant Heat Flux:
For laminar flow in a tube under constant heat flux condition, the Nusselt number is approximately equal to 4.36.

Therefore, the correct answer is option 'A' (4.36).
