A definitive estimate for the cost of a 20,000-ton/ year oxygen plant is $15M.
(a) Provide an order-of-magnitude estimate for a 30,000-ton/year facility.
(b) Assume that the AACE error limits apply to both estimates. Provide upper and lower estimates for the cost of the 30,000-ton/year facility.
(c) Assume the 20,000-ton/year facility was designed for Los Angeles and the 30,000-ton/year facility is for Anchorage. Adjust your estimate accordingly.
