5. Given the hydrostatic equation, APressure = -pgAh, where p = air density, g is the acceleration due to gravity, and h is the altitude, explain how much the pressure would change in Ib/in? going from sea level (0.000ft) to the top of Pikes Peak (14,110ft). Use appropriate significant figures, and express your answer in scientific notation. You can assume the density of the air is 2.519 x 10-3 slug/ft3. Key Concepts: Do you understand how many significant figures your end result should have? Remember that you do not apply the significant figure rule until the FINAL answer. Make sure you can manipulate units. Do you understand how to use scientific notation? Example: 5 x 102? Answer: 7.95 Ib/in?
