Question
You want to transfer No. 3 fuel oil (308API)from a storage tank to a power plant at a rate of 2000 bbl/day. The diameter of the pipeline is 1 1 2 in. sch 40, with a length of 1200 ft. The discharge of the line is 20 ft higher than the suction end, and both ends are at 1 atm pressure. The inlet temperature of the oil is 608F, and the transfer pump is 60% efficient. If the specific heat of the oil is 0.5 Btu/(lbm 8F) and the pipeline is perfectly insulated, determine:
(a) The horsepower of the motor required to drive the pump
(b) The temperature of the oil leaving the pipeline
Explanation / Answer
Power ={(2000*159*ro)/(24*60*60)}*9.8*20*0.348*100/60 in Watts. {The density of oil is???}
ro*V*g*20*0.348 = ro*V* 2.099*dt
dt =32.5F
Temperature =640.5F
