The barometer of a mountain hiker reads 930 mbars at the beginning of a hiking trip and 780 mbars at the end. Neglecting the effect of altitude on local gravitational acceleration, determine the verticl distance climed. Assume an average air density of 1.20kg/m^3

Question

earthcitizen · Answer

$$P _{2}-P _{1}=\rho g h$$

earthcitizen · Answer

$$P _{2 }=930 mbars =93000 Pa, P _{1}= 780mbars=78000 Pa$$

earthcitizen · Answer

$$\rho = 1.20kg/m^3, g=9.81ms ^{-1} and h= ?$$

earthcitizen · Answer

$$\therefore, 93000-78000= (1.20)*(9.81)*(h) $$

earthcitizen · Answer

h= 1274m
