Bernoulli/Pascal "Tarpaulin" Problem 1. The problem statement, all variables and given/known data "The construction of a flat rectangular roof (4.0m x 5.5m) allows it to withstand a maximum net outward force of 21 000 N. The density of the air is 1.29 kg/m^3. At what wind speed will this roof blow outward?" A1=22m^2 F=21000 N p=1.29 v1=0? 2. Relevant equations Bernoulli's Equation: P1-1/2p(v1)^2+pgy1=P2+1/2(v2)^2+pgy2 Pascal's Principle? F2=F1*(A2/A1) 3. The attempt at a solution 1/2(1.29)v1^2=1/2(1.29)v2^2 I believe this has something to do with Pascal's Principle, but I'm not quite sure. 2100=F1(A2/22) From here, I'm completely lost. On a side note, I have a quick question on Archimedes' Principle. The weight of the displaced fluid is normally found through the volume of the displaced fluid and the given density, correct? Thanks in advance.
