For the first few thousand feet above sea level the rate of pressure decrease is in the neighborhood of 1 inch of pressure for each 900 to 1000 ft.

在离海面几千英尺高度上(在拔海高度数千英尺以下)气压递减率大约是每900到1000英尺高度下降1英寸汞柱左右。

The result shows that non-equilibrium makes the flowing pressure decrease slow-ly.

结果表明：不平衡效应使得渗流过程中的压力下降缓慢。

The pressure is going to decrease along the way, but it's going to have to do more work So the majority in this case is right.

根据这个式子，做的功,因此多数派是正确的。

The assumptions of a 230 mph wind speed and a 1.2 psi rapid pressure decrease in about 1 second along with large and fast missiles is quite a force to design against.

The effects of depressurization on internal structures is not intuitively obvious to non-engineers, but a 20 foot wide by 20 foot high wall that sees a 1.2 psi rapid pressure decrease feels a load of about 70, 000 lbs of horizontal force.

If there was a failure in the air supply system then the pressure would decrease more slowly but still eventually match the outside air pressure.
