The exterior walls of a building may pose a fire hazard to the adjacent building within the same lot or across the property line. Therefore, an exterior wall's minimum required fire rating is a function of its distance from the adjacent building, defined as fire separation distance (FSD) by the International Building Code. What is the required minimum value of FSD for a non-load-bearing wall
(such as a glass curtain wall) so that the wall's fire rating may be zero?

A chemical engineer is considering two sizes of pipes for moving distillate from a refinery to the tank farm. A small pipeline will cost less to purchase (including valves and other appurtenances), but will have a high head loss and, therefore, a higher pumping cost. The small pipeline will cost $1.7 million installed and have an operating cost of $12,000 per month. A larger-diameter pipeline will cost $2.1 million installed, but its operating cost will be only $8000 per month. Which pipe size is more economical at an interest rate of 1% per month on the basis of an annual worth analysis? Assume the salvage value is 10% of the first cost for each pipeline at the end of the 10-year project.
