Part B. What is the force on the roof?

6. A strong wind reaches a speed of 40.0 m/s in Boulder, Colorado. Typical air density in Boulder in 1.14 kg/m, and the corresponding atmospheric pressure is 8.89 x 10N/m (10%) Calculate the pressure right above the roof of a enclosed house? (10%) If the roof has an area of 200 m, what is the pressure in the faucet?

    Every few years, winds in Boulder, Colorado, attain sustained speeds of 45.0 m/s (about 100 miles per hour) when the jet stream descends during early spring. Approximately what is the force due to the Bernoulli effect on a roof having an area of 245 m2? Typical air density in Boulder is 1.14 kg/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...

    Dorothy is up on her 10.0m by 17.0m roof enjoying the view of Kansas. Suddenly, a strong wind blows down her ladder, leaving her stranded. She knows that a high wind reduces the air pressure on the roof, and that there is a danger that the atmospheric pressure inside the house will blow the roof off. As the wind reaches a speed of 37.5m/s, she calls to her Auntie Em for help. Calculate the force on the roof.

    A hurricane wind blows across a 7.50 m × 18.7 mflat roof at a speed of 170 km/hr . A) Is the air pressure above the roof higher or lower than the pressure inside the house? B) What is the pressure difference? C) How much force is exerted on the roof? D) If the roof cannot withstand this much force, will it “blow in” or “blow out”?

  • A hurricane wind blows across a 8.00m×16.0m flat roof at a speed of 140 km/h ....

    A hurricane wind blows across a 8.00m×16.0m flat roof at a speed of 140 km/h . Part A: Is the air pressure above the roof higher or lower than the pressure inside the house? Pick one. Explain. The pressure above the roof is lower due to the lower velocity of the air. The pressure above the roof is lower due to the higher velocity of the air. The pressure above the roof is higher due to the lower velocity of...
