Atmospheric pressure

*P*(in lbs per square inch) under typical conditions can be approximately calculated by using the formula below, where*h*represents the number of feet above sea level. Homework Help ✎*P*= 14.7*e*^{−0.00003}^{h}What is pressure at sea level?

Use the formula to calculate the atmospheric pressure in the mile-high city of Denver, Colorado.

The lowest point in Death Valley is 285 feet below sea level. What is the atmospheric pressure in Death Valley?

*P* = 14.7*e*^{−0.00003(0)}

14.7 psi

*P* = 14.7*e*^{−0.00003(5280)}

*P* = 14.7*e*^{−0.00003(−285)}
