SUMMARY OF THE RESULTSThe Figure 2 presents the values of the linear pressure losses <strong>according</strong> <strong>to</strong> <strong>air</strong> velocity, for thestandard c<strong>on</strong>diti<strong>on</strong>s (20°C, 101325 Pa), and for a secti<strong>on</strong> of 300 mm × 300 mm. The linearpressure losses are due <strong>to</strong> the roughness of the inner surface of the <strong>duct</strong>boards and theturbulence possibly created by the links between each board.Linear pressure losses <strong>according</strong> <strong>to</strong> <strong>air</strong> velocity (rho = 1,2 kg/m3)Linear pressure losses (Pa/m)14,012,010,08,06,04,02,00,00,0 5,0 10,0 15,0 20,0Air velocity (m/s)Figure 2 : Linear pressure losses <strong>according</strong> <strong>to</strong> <strong>air</strong> velocity, for P8858 reference,300 mm × 300 mm5/10
