Here,
for the speed of wind = 180 km/hr
v = 180 * 1000/3600 m/s
v = 50 m/s
weight of the rope = pressure difference * area of roof
weight of the rope = 0.50 * 1.21 * 50^2 * 5.8 * 12
weight of the rope = 105270 N = 110000 N
the weight of the rope is 110000 N

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...
