- A 3-legged stool weighing 4.5-kg supports an 89-kg person. each leg of stool has a cross-sectional diameter of 1.4 cm and the weight of the person is evenly distributed, what is the pressure exerted on the floor by each leg in (Pa).The pressure exerted on the floor by a person’s shoe heel varies in direct proportion to his or her weight, andinversely proportional to the square of the diameter of the heel. Find the particular equation when a pressure of 29.1 psiresults from a man weighing 175 pounds wears shoes with a 2.55 inch diameter heel. Using the particular equation youfind, predict the pressure (to the nearest psi) under the ¼ inch spiked heel of a woman weighing 125 poundsOn average the diaphragm of an adult human canexert 10 kPa of pressure to expand the lungs and force airinto the lungs. Knowing this, if you took a hose down tothe bottom of a deep pool how far down could you gobefore you couldn’t breath through the tube anymore?
- Dew forms on one of the aircraft wings on the runway. A typical water droplet has an excess pressureof 56Pa above the surrounding atmosphere. Given that the air/water surface tension is 0.07N/m,calculate the droplet diameterThe gauge pressure in your car tires is 2.25 x 10° Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska.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.
- Saul ascends from the city of Tucson, Arizona, to the top of Kitt Peak, 2900 mabove sea level. Usually Saul will feel his ears “pop” as the pressure inside hisears attempts to maintain equilibrium with the surrounding air. However, onthis day, Saul has a cold and his Eustachian tube is clogged, causing atremendous pressure behind his 4.0 x 10^(-5) m^2 ear drum. What force does Saul feel pushing on his ears?

The average gauge pressure from the water is 8 psi. What is the total outward force on the window?A hurricane-force wind of 180 km/h blows across the face of a storefront window. Estimate the force on the 2.0 m x 3.0m window due to the difference in air pressure inside and outside the window. Assume the store isairtight so the inside pressure remains at 1.0 atm. (This is why you should not tightly seal a building in preparation for a hurricane.)
- A viewing window on the side of a large tank at a public aquarium measures 58 in. by 68 in. The average gauge pressure from the water is 3 psi. What is the total outward force on the window?lbWhen a submarine dives to a depth of 5.0 × 10^2 m, how much pressure, in Pa, must its hull be able to withstand?A hurricane force wind of 230 km/h blows across the face of a storefront window. Estimate the force on the 2.0 m X 3.0 m window due to the difference in air pressure inside and outside the window. Assume the store is airtight so the inside pressure remains at 1.0 atm. Express your answer to two significant figures and include the appropriate units.
