The area A is the cross-sectional area of the pipe.

Probably the two most important things are called cross-sectional area and shape.

The second factor is the amount of water and the cross-sectional area of the river.

Air pressure depends on speed and size (specifically the cross-sectional area).

The smaller the cross-sectional area, the greater the percentage of drop.

The core is characterized by its diameter or cross-sectional area.

This can be expressed as an effective cross-sectional area per nucleus.

As a consequence, only small cross-sectional areas of the material are used.

Where, A is the cross-sectional area of the control volume.

Skiers can reduce this force by reducing the cross-sectional area of their body.
