Unformatted text preview: # 2. [Designing a Heat Conductor] You are asked to design a cylindrical steel road 1.00 m long, with a circular cross section, that will conduct heat from a furnace at 400 ° C to a container of boiling water under one atmosphere. The boiler must produce steam at a rate of 1 g/sec. What must the rod’s diameter be? #3. [Solar Power] The intensity of solar radiation reaching the Earth’s upper atmosphere is about 1370 W/m 2 (the solar constant ). (a) Based on this value, what is the total power output of the Sun? Please be sure your reasoning is clear. (b) Assuming that the Sun’s emissivity is equal to 1, compute the surface temperature of the Sun. [ HINT : Possibly useful information may be found in the Astronomical Data table on page A8 in Appendix F at the back of your textbook.]...
