In: Misr Journal of Agricultural Engineering, 2003 v.20 (4), Special issue, 15-16 October, 2003 (part 2) 2003.v.20(4)SISummary: This paper aims to study the possibility of using the leaky pipes as a diffused-air aeration in the aquaculture systems. Air pressure in the pipe, ' standard oxygen transfer rate (SOTR). and standard aeration efficiency (SAE) were 'determined to evaluate the performance of these pipes under different air flow rates (14.1-106.0 m31h) and water hydrostatic pressures' (0.5-2.0 m H20) for jive and ten pipes on the line. The results indicated that the air pressure increased with increasing of both hydrostatic pressure and airflow rate. The effect of the hydrostatic pressure on the air pressure was higher than that of the air flow rate. The standard oxygen transfer rate (SOTR) increased with increasing the hydrostatic pressure in the aeration tank. Using ten leaky pipes on the air pipe caused an increase in the. standard oxygen transfer rate (SOTR) compared to the use of jive pipes treatment. The standard aeration efficiency (SAE) decreased with increasing the air flow rate. It could be concluded also that, the effect of air flow rate 011 the SAE is greater than that of the hydrostatic pressure. The results revealed also that the SAE increased with increasing the member of leaky pipes.
