Question: A hypodermic syringe is used to inject acetone at 700F into a laboratory equilibrium still operating at 5.0 psig. The syringe has a 1.5-in. barrel ID and is connected to the still by 5.09 ft of special hypodermic tubing having an ID of 0.084 in. What injection rate in gallons per minute would you expect for a force of 15 lbf applied to the syringe plunger? State your assumptions.
- Barometer = 750 mm Hg
- Viscosity = 0.35 cP
- Specific gravity = 0.7
