A cast-iron pipeline 2 m long is required to carry 3 million gal of water per day.
Question:
A cast-iron pipeline 2 m long is required to carry 3 million gal of water per day. The outlet is 175 ft higher than the inlet. The costs of three sizes of pipe when in place are as follows:
10-in. diameter................................. $11.40 per ft
12-in. diameter................................. $14.70 per ft
14-in, diameter................................. $16.80 per ft
Power costs are estimated at $0.07 per kilowatt hour over the 20-year life of the pipeline. If the line can be bonded with 6.0% annual interest, what is the most economical pipe diameter? The pump efficiency is 80%, and the water inlet temperature is expected to be constant at 42°F.
