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 due to the Bernoulli effect on a roof having an area of 220 m^2?

A) 1.24 × 10⁶ N
B) 2.48 × 10⁶ N
C) 3.72 × 10⁶ N
D) 4.96 × 10⁶ N

Answer 1

The force due to the Bernoulli effect on a roof with an area of 220 m² in Boulder, Colorado, is approximately 3.72 × 10⁶ N.

Step-by-step explanation:

The force due to the Bernoulli effect on a roof can be calculated using the formula:

Force = (0.5 * density * velocity^2) * area

Where the density of air in Boulder is 1.14 kg/m³ and the velocity is 45.0 m/s. Plugging in these values along with the given area of 220 m², the force is approximately 3.72 × 10⁶ N.
