Air line pipe with optimum flow and air quality. SmartPipe's smooth calibrated aluminum construction has a low friction coefficient, providing the best possible laminar flow. Full bore fittings further minimize pressure drop for optimum flow and energy efficiency. Leak-free connectors prevent air loss and wasted energy For each unit length, pressure loss can be cut with smooth bore piping made of copper, aluminum or stainless steel. With these materials, you can use a smaller size of pipe and still retain air sufficient velocity with minimal pressure drop. However, pressure loss could still occur if your piping system contains sharp turns of 90 degrees or more When measuring lengths of runs, add 5' of length for each pipe fitting. If carrying 120 PSI pressure these sizes will carry slightly more air than shown, or pressure loss will be slightly less than 1 PSI. If carrying 80 PSI pressure these pipes will carry slightly less air at 1 PSI pressure loss than shown in the chart Some leading compressed air professionals have determined that if the maximum velocity of the compressed air inside the pipe is kept between 20 and 30 feet per second, then minimal pressure drop will develop across reasonably long compressed air piping and fittings (for very long runs the piping must be oversized) The maximum temperature of most PVC pipe and fittings is 140F, and even at 110F you derate the pressure rating in half. So a pipe rated for 150 psi is now only good for 75 psi, because of the 110F temperature of the air running through it. Most small piston compressors can have air coming out 200F or higher, especially in the summer

Major losses create a pressure drop along the pipe since the pressure must work to overcome the frictional resistance. The Darcy-Weisbach equation is the most widely accepted formula for determining the energy loss in pipe flow. In this equation, the friction factor (f), a dimensionless quantity, is used to describe the friction loss in a pipe hose to minimize pressure drop in air lines. Friction of Air in Pipes Air pressure loss, psi in 100 ft. of clean commercial steel pipe. When a pump uses 10 cfm at 100 psi, it is using compressed to 2.46 cubic feet at 100 psi. The pump is then actually using 2.46 cubic feet at 100 psi, but the measurement of its consumption is on the basis of. Pressure drops are calculated by adding the length of tubing required to the equivalent feet (meters) of all fittings in the line.

We can calculate the resistance of our tool with the most hoods and ducting overhead, then add to that the resistance of all the pipe and fittings in their largest ducting run, and then. Pressure drop through the pipe is caused by the friction of the air mass making contact with the inside walls of the pipe. This is a function of the volume of flow through the pipe.
