Chapter 7 – Problem 7.8
7.8 A 2600 mm diameter 30 km long pipeline lifting water by roughly 100m is protected by 6×80 m3 compressor surge tanks (see Figure 5.26). If the compressors are turned on twice a day replenishing roughly 3% of air volume (assume 50% of the tank volume is compressed air under steady state conditions), how much compressed air is introduced into the pipeline each day? Is the density of water expected to remain constant all along the pipeline? Is the celerity expected to remain constant all along the pipeline?
