Question:

1. A cast-iron pipeline carries 4 million gallons of water (at 55°F) per day. Over a 3-mile seg-

ment of the pipeline the elevation decreases by 400 feet. The costs of installation for three pipe sizes are as follows:

12-in. (nominal) $115/ft 14-in. (nominal) $135/ft 16-in. (nominal) $155/ft Power costs are $0.075 per kWh over the expected 15-year lifetime of the pipe. If the pump efficiency is 56 percent, what is the most economical pipe diameter?
