12-198.

Assuming normal conditions, atmospheric pressure

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

Use the formula to calculate the atmospheric pressure under normal conditions 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 under normal conditions?

P = 14.7*e*^{−0.00003(0)}

14.7 Psi

P = 14.7*e*^{−0.00003(5280)}

P = 14.7*e*^{−0.00003(−285)}
