A hurricane wind blows across a 7.30 m x 18.5m flat roof at a speed of 150 km/hr What is the pressure difference? Express your answer with the appropriate units. How much force is exerted on the roof? Express your answer with the appropriate units.
A hurricane wind blows across a 6.00 m times 15.0 m flat roof at a speed of 190 km/hr.What is the pressure difference? Use 1.28 kg/m^3 for the density of air.How much force is exerted on the roof?If the roof cannot withstand this much force, will it "blow in" or "blow out"?Help?
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 . 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...
Roof 123 A storm blows wind across the top of a roof at a speed of y-26.5 m/s. Assume the air on the lower side of the roof (inside) is at rest and the roof is flat and has an area A- 39.3 m². The density of air is 1.28 kg/m". 1) What is the pressure differential across the top and bottom of the roof? Pa 2) What is the net lift force on the roof due to the storm?...
A 180-km/h wind blowing over the flat roof of a house causes the roof to lift off the house. Part A If the house is 5.8 m X 12.0 m in size, estimate the weight of the roof. Assume the roof is not nailed down. Express your answer to two significant figures and include the appropriate units. ? HÅ Value O O Units Fair = Submit Request Answer
Problem 10.49 A 180-km/h wind blowing over the flat roof of a house causes the roof to lift off the house. Part A If the house is 7.0 mx 13.0 m in size estimate the weight of the roof.

Question 7: During a hurricane, a 60 m/s gust blows across a 12 m by 10 m roof. Assume the air inside the house is stationary, what force does this create on the roof? What direction is this force? (Assume density of the air 1225 kg/m)
During a thunderstorm, winds with a speed of 45.7 m/s blow across a flat roof with an area of 618 m2 . Find the magnitude of the force exerted on the roof as a result of this wind. (Express answer in kN).
