Convective Heat Transfer over a Flat Plate: ConcepTest and Example Problem
Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.
Example Problem 1
A simplified version of a solar cell consists of a very thin semiconducting silicon layer. A layer of protective glass is glued to the silicon by an adhesive. The solar cell is 0.5 m long and 0.2 m wide. The air temperature is 25°C. It blows over the solar cell at a speed of 5 m/s. Calculate the average heat transfer coefficient, h̅. Report your answer in units of W/m2-K.
