Every few years, winds in boulder, colorado, attain sustained speeds of 45.0 m/s (about 100 mph) when the jet stream descends during early spring. approximately what is the force due to the bernoulli effect on a roof having an area of 230 m2? typical air density in boulder is 1.14 kg/m3 , and the corresponding atmospheric pressure is 8.89 × 104 n/m2 . (bernoulli’s principle assumes a laminar flow. using the principle here produces only an approximate result, because there is significant turbulence.)

265477.5 N

Explanation:

= Density of air = 1.14 kg/m³

v = Velocity of wind = 45 m/s

A = Area = 230 m²

From Bernoulli's principle we have the relation

Force is given by

Force due to the jet stream on the roof is 265477.5 N
