Every few years, winds in Boulder, Colorado, attain sustained speeds

Berikut ini adalah pertanyaan dari daruadiyaksa31 pada mata pelajaran Fisika untuk jenjang Sekolah Menengah Atas

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 equation on a roof having an area of 220m2? Typical air density in Boulder is 1.14kg/m3, and the corresponding atmospheric pressure is 8.89×104N/m2. (Bernoulli’s principle as stated in the text assumes laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)

Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Jawaban:

1.6 x 10^6 N.

Penjelasan:

The force due to the Bernoulli equation on the roof is approximately 1.6 x 10^6 N. This is calculated by using the formula for Bernoulli's principle,

which is F = P × A × V, where

F is the force

P is the atmospheric pressure

A is the area of the roof

V is the wind speed.

Plugging in the given values, we get F = (8.89 x 10^4 N/m^2) × (220 m^2) × (45 m/s) = 1.6 x 10^6 N.
