Force - A push or pull acting upon a body. In a hydraulic cylinder, it is the product of the pressure on the fluid, multiplied by the effective area of the cylinder piston. It is measured in pounds or tons. Friction - The resistance to fluid flow in a hy- draulic system.
temperature increase The pressure of a contained sample of gas can be increased by increasing its temperature, or by decreasing its volume, or by injecting additional mas â¦ s into it.
The key thing to know is that the wind pressure increases exponentially with speed. A doubling of the wind speed increases the pressure by a factor of four. A tripling of the wind speed increases the pressure by a factor nine! Don't Be Fooled by the. 'Zone of Complacency'.
