Question:medium

The primary mode of heat transfer to the workpiece in a salt bath furnace is

Show Hint

To classify heat transfer modes instantly:
• Solid-to-Solid contact \(\implies\) Conduction
• Fluid-to-Solid interaction \(\implies\) Convection
• Electromagnetic wave propagation \(\implies\) Radiation Since a salt bath consists of liquid (molten salt) touching a solid (workpiece), it is fundamentally fluid-solid convection.
