    This equality of pressure is known as Pascal's law, and is illustrated in Figure 1.9 where a force of 5 kg f is applied to a piston of area 2 cm 2. This produces a pressure of 2.5 kg f cm −2 at every point within the fluid, which acts with equal force per unit area on the walls of the system. Figure 1.9.
