Suppose a gas that absorbs solar radiation has a uniform mixing ratio of 1 g kg-' and an absorption cross section of 5 m2 kg-1. Assume an isothermal atmosphere with T = 260 K, and a surface pressure of 1.025 x 10^5 Pa, and that the sun is directly overhead. If the frequency range at which the absorption is taking place contains 5% of the total solar energy flux, what is the heating rate in degrees per day at the level of maximum energy absorption and what is the heating rate one scale height above and below the level of maximum energy absorption? Use the globally averaged insolation, and please explain the steps of the answer.

Problem 1: This is textbook problem 4.51 (page 224) Steam at 1800 lbf/in2 and 1100 °F enters a turbine operating at steady state. As shown in the Figure, 20% of the entering mass flow is extracted at 600 lbf/in2 and 500 °F. The rest of the steam exits as a saturated vapor at 1 lbf/in2 . The turbine develops a power output of 6.8×106 Btu/h. Heat transfer from the turbine to the surroundings occurs at a rate of 5×104 Btu/h....
