Question:

As shown in Fig. 2.6 for the U.S. standard atmosphere, the troposphere extends to an altitude of $11 \mathrm{~km}$ where the pressure is $22.6 \mathrm{kPa}$ (abs). In the next layer, called the stratosphere, the temperature remains constant at $-56.5^{\circ} \mathrm{C}$. Determine the pressure and density in this layer at an altitude of $15 \mathrm{~km}$. Assume $g=9.77 \mathrm{~m} / \mathrm{s}^{2}$ in your calculations. Compare your results with those given in Table C. 2 in Appendix C.
