They are widely used in industries requiring efficient heat transfer solutions, such as in power plants, chemical processing units, and refrigeration systems.

Q12. What is the efficiency of studded tubes compared to other finned tubes?

Answer: Studded tubes are highly efficient in transferring heat because of the increased surface area created by the studs (or projections) attached to the tube. These tubes are particularly effective in applications where high turbulence is needed for efficient heat transfer. Compared to other finned tubes, studded tubes can offer superior performance in high-viscosity or high-dirt-load environments.

Q13. How does a finned tube increase the heat transfer rate?

Answer: Finned tubes enhance heat transfer by increasing the surface area in contact with the surrounding fluid, allowing for more effective heat exchange. The fins, whether helical, spiral, or straight, disrupt the boundary layer of the fluid, improving fluid flow and heat dissipation. This results in better thermal efficiency and reduced energy consumption.
