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.
This is because the static pressure is increased from the additional weight of water above. This increase in pressure is linearly related to the depth, wâ¦hich at sea level adds about 4.5 psi for every 10 feet of depth.
