Critical Thinking Questions
1. Describe an occasion in which an explanatory sketch would be used.
2. While it seems rather obvious that engineers need to consider the end user, how might this perspective get lost in the design process?
3. Give an example of a product in which ductility would be a particularly important factor. Explain your answer.
4. Why might a prototype be built with different materials than those used in the final product?
5. Which of the careers in engineering discussed in the unit appeals to you the most and why?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
