Can A Bullet Crush The Skull? The obvious answer to this is a big yes! The reason for this is that a bullet moves at a velocity that is quicker than the speed of sound and is usually released with such a force that whatever object it comes in contact with is usually destroyed. Last Line. By now you should know how much pressure to break a skull.

The pressure class or rating for flanges is given in lbs. For example: 150lb, 150 lbs, 150#, or class 150 – are all equivalent. The flange class or pressure rating system extends to gaskets designed for those flanges. So, for example, a class 150 gasket is designed to seal under a load of up to 150 lbs of pressure in a class 150 flange.

Another factor that is used to establish the maximum flow line is a pressure ratio near or equal to 1. The 50% speed line may be considered an example of this. The shape of Figure 5.2's speed lines provides a good example of why it is inappropriate to use the term choke in association with a maximum flow of all centrifugal compressor speed lines.

This small amount of condensed water cannot exert much pressure on the inside walls of the can, and none of the outside air can get back into the can. The result is the pressure of the air pushing from the outside of the can is great enough to crush it. The sudden collapsing of an object toward its center is called an implosion.
