A liquid (SG = 0.8 and μ = 5 CP = 0.00336 lbm/ft s) from a solvent recovery plant is being pumped
from a vessel into a reactor. The flow rate to the rector is 100 GPM (0.2228 ft³/s,) and the line,
schedule 40-carbon steel (a = 0.0018 in). The pressure in the vessel is 15 psig and the reactor is
pressurized to 65 psig. The flow into the reactor is 25 ft below the level in the vessel as shown in
the drawing. The centrifugal pump is located 5 ft below the level in the vessel.

Dye for our new line of blue jeans is being blended in a mixing tank. The desired color of
blue is produced using a concentration of 1500 ppm blue dye, with a minimum acceptable
concentration of 1400 ppm. At 9 A.M. today the dye injector plugged, and the dye flow was
interrupted for 10 min, until we realized the problem and unclogged the nozzle. For how
many minutes was the flow leaving the mixer off-specification (< 1400 ppm)? How many
gallons of off-spec dye were made? See Fig. P5-15.
