Pressure is the amount of force applied to a unit area and is calculated by dividing the applied force by the area of the contact surface that the force is acting on.
The SI unit for pressure is the pascal (Pa) which is the name given to one newton per square metre (N/m2).
Pascal’s law states that a change in pressure at any point in an enclosed fluid, at rest, is transmitted undiminished to all points in the fluid.
