This lesson allows you to test yourself on the material covered in the lesson on Convection, and to determine the level to which you have met the learning outcomes.
Suggested Response - Q1
* The film heat transfer coefficient is dependent on which of the following parameters?
a) The material of the heat transfer surface
b) The temperature of the heat transfer surface
c) The surface area of heat transfer
d) The viscosity of the fluid
Response:
The correct answer is d, the viscosity of the fluid. The film heat transfer coefficient is dependent on variables of the fluid, not the heat transfer surface. Therefore, the only correct answer is d, since viscosity is a property of the fluid and not of the heat transfer surface.
