Common Pneumatic Formulas. Air Valves help to regulate pressure in the cylinder and are sized for flow capacity (Cv). Cv is based on the specific cylinder stroke & travel time requirements, as well as piston size. Cv is a coefficient that measures the quantity of air a device can pass.
BASIC PNEUMATIC FORMULAS. Basic Valve Sizing: Air valves are sized for flow capacity (Cv) based upon a given cylinder piston size, stroke and travel time requirements. Cv us actually a flow coefficient that measures the amount of air a device can pass. The following formula can be used for air valve sizing:

Identify and explain basic components and functions of fluid power devices. Differentiate between the characteristics of pneumatic and hydraulic systems. Calculate values in a fluid power system utilizing Pascal's law. Calculate flow rate, flow velocity and mechanical advantage in a hydraulic system.
Pneumatics is the utilization of compressed air in science and industry in order to perform mechanical work and control. We can either talk about pneumatics or pneumatic systems. In this course we define pneumatics as the control and transfer of power by using compressed air.
Gear Displacement Calculation: The volumetric displacement of a gear pump or motor can be approximated by measurement of the internal parts and substituting the values in the following formula: V = 6.03 × W × (2 x D -L) × (L - D ÷ 2) Where. L. = displacement in in3/rev. = gear width in inches.
