In Problem 9.4.1, if insulation were absent what minimum flow rate could be tolerated? Compare the HP requirements in both cases. Assume 15 psi pump suction pressure
In Problem 9.4.1, if insulation were absent what minimum flow rate could be tolerated? Compare the HP requirements in both cases. Assume 15 psi pump suction pressure.
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).
