E Microsoft Word - cphwch12FluidsinMution 11) A at rectangular thin roof has dimensions 5.0 m by 6.3 In. Wind blows across the top of the roof (point 1) at speed v1, but the air just below the roof (point 2) is at rest. If the pressure P2 below the roof is greater than the pressure P1 above the roof, then the pressure difference (AP = P2 B) can cause a lifting force on the roof. A force of 22 000 N will just barely lift this roof. The density of the air is 1.29 kg/m3. (a) Determine the pressure difference required to just barely lift the roof. (b) Determine the wind speed (in m/s and \"'41:th 1 . 14:? P, miles/hr) across the top of the roof, so the roof is barely being lifted. 2 . P 2
