Pressure Drop

Uploaded by

dept.processnamo

The document contains a table with data on pressure drop in compressed air pipelines of different diameters. It shows the pressure drop in kg/cm2 and psi for various volume flows between 0.1-100 m3/min and pipe sizes from 1-4 inches. It notes that pressure drops above 1 kg/cm2 (14-15 psi) may not be accurate for the calculation method used.
