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.
It also increases. 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.
