From the second diagram above we can estimate the friction loss to be approximately 0 4 psi 50 ft. Air fittings affect flow and increase pressure drop. Then assume 5 loss per 100 of air line. Air flow pressure calculator the gates air flow pressure calculator helps you understand your operation s air flow issues so you can find effective solutions to reduce maintenance eliminate hose malfunctions avoid costly downtime and improve operational efficiency.

Pressure drop is a phrase that refers to the instances when pressure loss occurs inside a compressed air system. Pressure drop online calculator calculation of pressure drops of flowing liquids and gases in pipes and pipe elements laminar and turbulent flow. The friction loss in a 10 ft hose can be calculated as 0 4 psi 50 ft 10 ft 50 ft 0 08 psi. Example pressure loss in compressed air hose.

This can happen at numerous points between the air tank and end point tools if anything stands in the way to inhibit the flow of pressurized air. If your air line is between 1 2 i d. Based on 150 cfm 100 psi through 50 feet of compressor air hose. Online calculator to quickly determine pipe sizing by pressure loss for air.
