As a fuel saving measure, commercial jets cruise at an altitude of about 10 km. while cruising at an altitude of 10 km, a small leak occurs in one of the window seals in the passenger compartment of an airbus. within the passenger compartment, the pressure and temperature are, respectively, 1.05 atm and 20°c and the pressure outside the craft is 0.274 atm. model the air as an ideal fluid to find the speed (in m/s) of the stream of air flowing through the leak. (assume the density of air to be 1.20 kg/m3.)

= 357.26 m/s

Explanation:

Given:

first convert both pressures to pascals

Outside pressure = 0.294 atm = 0.294 × 101300 =   29782.2 Pascals

Inside pressure = 1.05 atm = 1.05 × 101300 = 106365 Pascals

Now, using the Bernoulli's equation

, we have

where

P is the pressure

v is the velocity

ρ is the density

i denotes the inside

o denotes the outside

the speed inside is approximately zero,thus

or

= 357.26 m/s

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
