Explain what is the pressure difference.
How much force is exerted on the roof. What is the pressure difference. How much force is exerted on the roof. Use 1 28 kg m 3 for the density of air. Is the air pressure above the roof higher or lower than the air pressure inside the house.
A is the pressure above the roof higher or lower than the ressure inside the house. How much force is exerted on the roof. P 1 2 1 29 33 33 2 716 n m2 or pa pressure above the roof 101325 716 100 609 pa. B what is the pressure difference δp pinside poutside.
Air flows through the tube shown in figure p63 at a rate of 1200 cm 3 s. A hurricane wind blows across a 6 0mx15 0m flat roof at a speed of 130 km h. D if the roof cannot withstand this much force will it blow in or blow out. A is the air pressure above the roof higher or lower than the pressure inside the house.
A hurricane wind blows across a 7 50 m times 11 2 m flat roof at a speed of 190 km hr. Use 1 28 kg m 3 for the density of air. Inner force if of 9 6 10 6 n. C how much force is exerted on the roof.
What is the pressure difference. Pressure inside the house is still air at 101325 pa. Air flows through the tube shown in figure p64. If the roof cannot withstand this much force will it blow in or blow out.
A is the air pressure above the roof higher or lower than the pressure inside the house. A hurricane wind blows across a 6 0 m x 15 m flat roof at a speed of 130 km hr. A hurricane wind blows across a 6 00 m times 15 0 m flat roof at a speed of 190 km hr. If the roof can t withstand this much force will it blow in or blow out.
