Explanation:
Evaporation at the liquid-vapor interface:
- When evaporation takes place at the liquid-vapor interface, the heat transfer is solely due to free convection.
- This means that heat is transferred through the movement of the fluid itself.
Film coefficient relation:
- The film coefficient in this case can be related using the Nusselt number (Nu) which follows the relation: Nu = f1(G r) f2(P r).
- Here, Nu is the Nusselt number, G r is the Grashof number, and P r is the Prandtl number.
- The function f1 and f2 are dimensionless functions that depend on the flow regime and fluid properties.
Answer:
- The correct relation for the film coefficient in this scenario is given by: Nu = f1(G r) f2(P r).
- This relation takes into account the Grashof and Prandtl numbers which are important parameters in free convection heat transfer.
- Therefore, option 'A' is the correct answer for this question.
