Homework 9 (11%) Problem 9: 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 235 m-? Typical air density in Boulder is 1.14 kg/m', and the corresponding atmospheric pressure is 8.89 x 10# N/m. (Bernoulli's principle assumes a laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.) Grade Summary F = N Deductions 0% Potential 100%
