A house is to be designed to withstand hurricane-force winds. The maximum wind velocity is 88 m s . The surface area of the roof is A = 450 m^2 . If the density of air is ρ = 1.03 kg m^3 , how much force must the roof supports be able to withstand?
). A wind turbine in the hurricane region has not been destroyed by the storm. If boundary layer winds were approximately the same speed as that calculated in question 4, would this turbine be able to produce energy? Why or why not? b). Normally (i.e. not in a hurricane) this large turbine, which sweeps out an area of 7.5 m2, operates in typical local winds of 12 km/hr at an air density of 1.2 kg/m3. Roughly how much power would...
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...
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”?
4.29 A structure is designed with a capacity to withstand a wind velocity of 150 kph; i.e., any wind velocity up to 150 kph will not cause damage to the structure. In a hurricane-prone area, the maximum wind velocity during a hurricane may be modeled as an extreme Type / asymptotic distribution with a mean velocity of 100 kph and a c.o.v. of 0.45. (a) For a structure with the above wind-resistant capacity, what would be the probability of wind...
A wind turbine is rotating at 15 rpm under steady winds flowing through the turbine at a rate of 43000 kg/s. The tip velocity of the turbine blade is measured to be 250 km/h. Assume 180 kW power is produced by the turbine and answer the questions that follow. Take the density of air to be 1.31 kg/m3 Determine the average velocity of the air. (You must provide an answer before moving to the next part.) The average velocity of...
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 10'N/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?
presents one method for modeling this problem. The construction of a flat rectangular roof (4.09 m × 7.90 m) allows it to withstand a maximum net outward force of of 3.90 × 104 N. The density of the air is 1.29 kg/m3. At what wind speed will this roof blow outward
The area of the kite is A=4m2. The wind speed is v=9m/s. The density of air is ρ=1.29kg/m3. If the kite is designed such that the air is stationary on the inner surface, how much force (unit N, only keep the integer numbers) can the kiteboarder expect the kite to generate?
