A box-shaped metal can has dimensions 8 in by 4 in by 10 in high. All the air is removed from inside the can. Find the force reverted by the outside air on one of the 8x10 in sides. The weight density of air is 0.08 lb/ft^

Atmospheric pressure is about 1.00 × 105 Pa on average. What is the downward force of the air on a desktop with surface area 1.01 m2?

An airplane flies on a level path. There is a pressure difference of 618 Pa between the lower and upper surfaces of the wings. The area of each wing surface is about 100 m2. The air moves below the wings at a speed of 80.5 m/s. A.)Estimate the weight of the plane. B.)Estimate the air speed above the wings. Density of air is 1.29 kg/m3.

If 1 mol of Argon atoms strike at a wall with an area of 10 cm² at an angle of 90 degrees per second. What is the pressure they exert if they have a speed of 450 m/s?

An airconditioning system requires a 35mlong section of 15cm diameter duct work to be laid underwater. Determine the upward force the water will exert on the duct. Take the densities of air and water to be 1.3 kg/m3 and 1000 kg/m3, respectively.

A student enters in a Physics lab wants to know the atmospheric pressure, how he can measure it? Through certain device he founds that its value is 1.083 bar, if some amount of oxygen gas is introduced in the space above the Mercury level, due to which this level falls by 5 cm. Predict the volume of oxygen gas introduced above the Mercury level, if it is assumed that its height in a tube is 1 m with 2 cm2 area of cross section.

The bottom of a rectangular swimming pool is 15 m × 25 m. If the atmospheric pressure above the swimming pool changes from 738 to 768 mm of mercury, determine the amount by which the force on the bottom of the pool increases? (Assume the density of mercury is 13.6 ✕ 103 kg/m3.)

A fish tank has dimensions 42 cm wide by 1.0 m long by 0.80 m high.If the filter should process all the water in the tank once every 3.0 h, what should the flow speed be in the 3.0-cm- diameter input tube for the filter?Express your answer to two significant figures and include the appropriate units.

A viewing window on the side of a large tank at a public aquarium measures 50 in. by 60 in. The average gauge pressure from the water is 8 psi. What is the total outward force on the window?

An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road.
