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.
Another term for water pressure. Pressure is directly affected by elevation change, and each 2.31 vertical feet of change upwards will decrease pressure by 1 psi in a holding tank.That is why such enormous pressures exist in the deep ocean; enough to crush a submarine as depth increases.f you have 5 sprinklers on one lateral line you will have much higher flow and lower pressure. Higher flow = less pressure. It's not an issue of hey, we need more water so crank up the pressure, it's an issue of we need more water, so increase the pipe size so we don't lose more pressure to friction loss.
