The compressed air requirements of a textile factory are met by a large compressor that draws in 0.6 m3 /s air at atmospheric conditions of 20°C and 1 bar (100 kPa) and consumes 320 kW electric power when operating. Air is compressed to a gage pressure of 8 bar (absolute pressure of 900 kPa), and compressed air is transported to the production area through a 15-cm-internal-diameter, 84-m-long, galvanized steel pipe with a surface roughness of 0.15 mm. The average temperature of compressed air in the pipe is 65°C. The compressed air line has 8 elbows with a loss coefficient of 0.6 each.
If the compressor efficiency is 82 percent, determine the pressure drop and the power wasted in the transportation line.
