1. The problem statement, all variables and given/known data A 190 km/h wind blowing over the flat roof of a house causes the roof to lift off the house. If the house is 6.5m x 15m in size, estimate the weight of the roof. Assume the roof is not nailed down. 2. Relevant equations Bernoulli's equation : P1 + 1/2pv^2 +pgy = P2 + 1/2pv^2 + pgy 3. The attempt at a solution i reduced the equation down to 1/2pv^2 to get pressure which numerically was 1671.3 and then i multiplied that by the area which i calculated to be 97.5 m^2, to get the force. I was clueless on how to approach this problem, but im even more confused now. please help.
