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.
Pressure can be exerted on gases more easily than on liquids and solids.A pressure cooker makes use of this property of matter. By increasing the pressure inside the cooker, it increases the temperature at which water boils.
