Thats the way I did. I am not sure is it right or wrong: First , Head required to overcome friction Losses and to maintain velocity head is to be calculated. Q= 5000 l/s = 5 m³ /s , A= 0.6 * 0.6 = 0.36 m² , Av . Velocity = Q/A =13.88 m/s Velocity head = V²/2g = 9.83 m of air coloumn ...

Homework Statement 1. the average velocity of the air to meet the required volume flow rate, 2. the pressure a fan needs to produce to overcome the frictional losses in the duct, 2. Relevant Information Duct size - 600 mm x 600 mm which operates at 3 Pa/m. The air path is 87 meters from...
