Find the total pressure for a mixture that contains four gases with partial pressures of 5.00 kPa, 4.56 kPa, 3.02 kPa, and 1.20 kPa.

Air is a mixture of gases. By percentage, it is roughly 78 percent nitrogen, 21 percent oxygen, and 1 percent argon. (There are trace amounts of many other gases in air.) if the atmospheric pressure is 760 mmHg, what are the partial pressure of nitrogen, oxygen, and argon in the atmospheric?

A tire is inflated to a gauge pressure of $28.0$ psi at $71^{\circ} \mathrm{F}$. Gauge pressure is the pressure above atmospheric pressure, which is $14.7 \mathrm{psi}$. After several hours of driving, the air in the tire has a temperature of $115^{\circ} \mathrm{F}$. What is the gauge pressure of the air in the tire? What is the actual pressure of the air in the tire? Assume that the tire volume changes are negligible.

When the shot whose path is shown by the blue graph is released at an angle of

$$35 ^ { \circ }$$

its height, f(x), in feet, can be modeled by

$$f ( x ) = - 0.01 x ^ { 2 } + 0.7 x + 6.1$$

where x is the shot’s horizontal distance, in feet, from its point of release. Use this model to solve and verify your answers using the blue graph. What is the maximum height of the shot and how far from its point of release does this occur?

Order the pressure of fluids at various depths and elevations. Circle the examples of atmospheric pressure. Then, describe the pressure in the other examples.

A mercury manometer $(\rho= 13600 ~\mathrm{\frac{kg}{m^3}})$ is connected to an air duct to measure the pressure inside. The difference in the manometer levels is 30 mm, and the atmospheric pressure is 100 kPa.

(a) Determine if the pressure in the duct is above or below the atmospheric pressure.

(b) Determine the absolute pressure in the duct.

Barometric pressure is a linear function of altitude. At an altitude of 2 kilometers, the barometric pressure is $600 \mathrm{mmHg}$, At 7 kilometers, the barometric pressure is $300 \mathrm{mmHg}$. Find a formula for the barometric pressure as a function of altitude.
