Experimental and theoretical methods to evaluate the pressure losses in air distribution lines
No full textModern pipes for compressed air distribution lines are made of aluminium alloy and built by means of manufacturing extrusion process. This kind of pipes needs of suitable mathematical formulation providing performances, in terms of pressure drop and flow-rate. To this aim in this work a methodology based both on experimental tests and on theoretical approach was carried out. Analytical formulations were performed providing best experimental data fitting and range of applicability. Performances of most common line components (straight pipes, elbows, straight fittings and tees) made of different commercial sizes were evaluated carrying out experimental tests by means of a properly instrumented test bench. Experimental and theoretical results were in good agreement, thus validating the proposed formulatio
