An additive having a viscosity of 2 cP and a density of 50 lbm=f t3 is fed from a reservoir into a mixing tank. The pressure in the reservoir and in the tank is 1 atm, and the level in the reservoir is 2 ft above the end of the feed line in the tank. The feed line contains 10 ft of 1/4 in. sch 40 pipe, four elbows, two plug valves, and one globe valve. What will the flow rate of the additive be, in gpm, if the valves are fully open?
