So in a spacecraft with regular air at 1 atm pressure, a hole gets punched in it (depressurizing it). I'm looking for the Exit Velocity of the air at t=0.
Using Units:
Internal Pressure: Pi = 1 atm = 101300 [kg / m*s2]
Air Density: [itex]\rho[/itex] = 1.2 [kg / m3]
And Equation:
Pi = 0.5 * [itex]\rho[/itex] * (Ve2)
...turns into
Ve = √( 2*Pi / [itex]\rho[/itex] )
The answer I get is Ve = 410 [ m2 / s2 ]
How is Distance2 over Time2 a Velocity in this context?
I'm hoping to compare another object's relative wind-speed against this, and I'm not sure how.
Would a stationary object next to the escaping air feel like it's going 410 [m/s]?
Thanks in advance
