Question
Every few years, winds in Boulder, Colorado, attain sustained speeds of 45.0 m/s (about 100 mi/h) when the jet stream descends during early spring.
Approximately what is the force, in units of newtons, due to the Bernoulli effect on a roof having an area of 220 m^2? Typical air density in Boulder is 1.14 kg/m^3, and the corresponding atmospheric pressure is 8.89 x 10^4 N/m^2. (Bernoulli's principle assumes a laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)
