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.

pneumatic. Learning Outcomes. After completing this lesson you will be able to. compare the relative compressibility of water and air, and relate this property to their ability to transmit force in hydraulic and pneumatic systems. identify examples where hydraulic and pneumatic systems are used.
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:
The hydraulic gradient (grade line) is defined as an imaginary line above a pipe so that the vertical distance from the pipe axis to the line represents the pressure headat that point. If a row of piezometers were placed at intervals along the pipe, the grade line would join the water levels in the piezometer water columns.
