Problem 9.4.1

An 8 in. nominal diameter pipe is used to move heavy crude oil from a heated storage tank to a refinery 12 miles away. The inlet temperature is 180°F and the crude oil has the following characteristics:

If the outlet temperature cannot drop below 150°F, what minimum flow rate needs to be maintained in the pipeline? Use the MIT equation and 0.002 in. pipe roughness, 70°F soil temperature, 36 in. burial depth, and 0.25 in. insulation, with K=0.02 Btu/hr/ft/°F. The K value for soil=0.6 Btu/hr/ft/ °F. Pipeline pressures are limited to ANSI 600 rating (1440 psi).

### If you were to select a person at random, what is the probability that they would have an IQ score of 130 or more, assuming the scores are distributed Normally

If you look at the scores on most IQ tests, they have a mean of 100 and a standard deviation of 15. For class discussion: (a) Why do you think….
