CPM Homework Help : A2C Problem 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 = 14.7e^−0.00003^h
1. What is normal pressure at sea level?
2. Use the formula to calculate the atmospheric pressure under normal conditions in the mile-high city of Denver, Colorado.
3. The lowest point in Death Valley is 285 feet below sea level. What is the atmospheric pressure in Death Valley under normal conditions?

Hint (a):

P = 14.7e^{−0.00003(0)}

Answer (a):

14.7 Psi

Hint (b):

P = 14.7e^{−0.00003(5280)}

Hint (c):

P = 14.7e^{−0.00003(−285)}
