*The pressure difference measured by a vertical U-Tube manometer can be calculated as - check Velocity Pressure Head.*A water manometer connects the upstream and downstream pressure of an orifice located in an air flow.A smaller scale demonstration of this phenomenon is briefly explained.

In fact, normal air pressure is strong enough to crush a metal container when not balanced by equal pressure from inside the container.

A dramatic illustration of atmospheric pressure is provided in this brief video, which shows a railway tanker car imploding when its internal pressure is decreased.

Accuracy can be improved by inclining the u-tube manometer.

The figure bellow indicates a u-tube where the left tube is connected to a higher pressure than the right tube.

Note that the left and the right tube must in the same declined plane for the angle to the horizontal plane to be correct.

The pressure difference in a inclined u-tube manometer can be expressed as Add standard and customized parametric components - like flange beams, lumbers, piping, stairs and more - to your Sketchup model with the Engineering Tool Box - Sketch Up Extension - enabled for use with the amazing, fun and free Sketch Up Make and Sketch Up Pro .

At sea level, this pressure is roughly the same as that exerted by a full-grown African elephant standing on a doormat, or a typical bowling ball resting on your thumbnail.

These may seem like huge amounts, and they are, but life on earth has evolved under such atmospheric pressure.

One pascal is a small pressure; in many cases, it is more convenient to use units of kilopascal (1 k Pa = 1000 Pa) or bar (1 bar = 100,000 Pa).
