(Heat transfer) During the day, heat is absorbed by many objects, such as cars, roofs, and brick walls. This heat is then radiated back into the environment during the cooler evening hours. Using Stefan-Boltzmann’s Law, E = e × σ × T4 (see Exercise 7), write a C++ program that determines the amount of radiation for the objects listed in the following table. Your program should request the object’s average surface temperature and emissivity, and then calculate and display the heat radiated. Complete the following chart, making three runs of the program:
Substance | Average Surface Temperature(°Celsius) | Emissivity | Heat Radiated (watts/m2) |
Automobile | 47 | .3 |
|
Brick | 45 | .9 |
|
Commercial roof | 48 | .05 |
