1. The problem statement, all variables and given/known data The roof of a house has an area of 92.8 m^2. In a violent storm the air blows across the roof at a speed of 106.8 km/hr. 2. Relevant equations Assuming that the air has a density of 1.25 kg/m^3, what pressure difference is created by the storm between the air outside and inside the house? 3. The attempt at a solution Pressure/s = Area * density / speed (m/s) = 92.8 * 1.25 / (106.8/3.6) = 3.91 atm*s how do i find the time? or am i doing the whole thing wrong?
