Every few years, winds in Boulder, Colorado, attain sustained speeds of 45.0 m/s (about 100 mi/h) when the jet stream descends during early spring.
Approximately what is the force, in units of newtons, due to the Bernoulli effect on a roof having an area of 220 m^2? Typical air density in Boulder is 1.14 kg/m^3, and the corresponding atmospheric pressure is 8.89 x 10^4 N/m^2. (Bernoulli's principle assumes a laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)

- How many cubic meters of helium are required to lift a balloon with a 400-kg payload to a height of 8 000 m? Take He = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression air = 0ez/8, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.arrow_forwardWhy does atmospheric pressure decrease more rapidly than linearly with altitude?arrow_forwardBecause atmospheric pressure is about 105 N/m2 and the area of a persons chest is about 0.13 m2, the force of the atmosphere on ones chest is around 13 000 N. In view of this enormous force, why dont our bodies collapse?arrow_forward
- Every few years, winds in Boulder, Colorado, attain sustained speeds of 43.0 m/s (about 100 mph) when jet steam descends during early spring. Approximately what is the force due to the Bernoulli equation on a roof having an area of 220m2? Typical air density in Boulder is 1.14kg/m3, and be corresponding atmospheric pressure is 8.89104 N/m2. (Bernoulli’s principal as stated in the text assumes laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)arrow_forwardThe Bernoulli effect can have important consequences for the design of buildings. For example, wind can blow around a skyscraper at remarkably high speed, creating low pressure. The higher atmospheric pressure in the still air inside the buildings can cause windows to pop out. As originally constructed, the John Hancock Building in Boston popped windowpanes that fell many stories to the sidewalk below. (a) Suppose a horizontal wind blows with a speed of 11.2 m/s outside a large pane of plate glass with dimensions 4.00 m 1.50 m. Assume the density of the air to be constant at 1.20 kg/m3. The air inside the building is at atmospheric pressure. What is the total force exerted by air on the windowpane? (b) What If? If a second skyscraper is built nearby, the airspeed can be especially high where wind passes through the narrow separation between the buildings. Solve part (a) again with a wind speed of 22.4 m/s, twice as high.arrow_forwardA fire hose has an inside diameter of 6.40 cm. Suppose such a hose carries a flow of 40.0 LIS starting at a gauge pressure of 1.62106 N/m2. The hose goes 10.0 m up a ladder to a nozzle having an inside diameter of 3.00 cm. Calculate the Reynolds numbers for flow in the fire hose and nozzle to show that the flow in each must be turbulent.arrow_forward
- A submarine is stranded on the bottom of the ocean with its hatch 25.0 m below surface. Calculate force needed to open the hatch from the inside, given it is circular and 0.450 m in diameter. Air pressure inside the submarine is 1.00 atm.arrow_forwardEvery few years, winds in Boulder, Colorado, attain sustained speeds of 45.0 m/s (about 100 mph) when the jet stream descends during early spring. Approximately what is the force due to the Bernoulli equation on a roof having an area of 220m2 ? Typical air density in Boulder is 1.14kg/m3 , and the corresponding atmospheric pressure is 8.89 × 104 N/m2 . (Bernoulli’s principle as stated in the text assumes laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)arrow_forwardA building is to be designed to withstand hurricane-force winds. The maximum wind velocity is v=89 ms. The surface area of the roof is A=450m . If the density of air is ρ=1.027kgm3 , how much force must the roof supports be able to withstand?arrow_forward
- The construction of a flat rectangular roof (5.54 m x 6.63m) allows it to withstand a maximum net outward force of 1.94 x 104 N. The density of the air is 1.29 kg/m3. At what wind speed will this roof blow outward ?arrow_forwardAt the top of a mountain the windspeed is recorded at 350km/hr. If a house on top the mountain has a roof with dimensions 3.5m by 4.5m what is the force (in N) due to the Bernoulli effect? Assume there is laminar flow and air density is 1.123 kg/m^2.arrow_forwardA wind with speed 40 m/s blows parallel to the roof of a house. The area of the roof is 250 m². Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be (Pair 1.2 kg/m³) =arrow_forward
