Chapter 18, Problem 18.28PP

For an aeration process, a sewage treatment plant requires $3000$ cfm of compressed air. The pressure must be $80$ psig, and the temperature must be ${120}^{\circ }F$. The compressor is located in a utility building, and $180$ ft of pipe is required. The line also contains one fully open butterfly valve, $12$ elbows, four tees with the flow through the run, and one ball-type check valve. Specify a suitable size of Schedule $40$ steel pipe, and determine the required pressure at the compressor.
