![Experiment Data
Take the following data for the syringe injection pump
Q/
Inner diameter of syringe barrel: D = 1.5 cm
Inner diameter of the needle shaft of the syringe: d = 0.5 mm
The thread pitch of lead screw: pt = 0.75 mm
Lead screw rotation velocity (rpm): n
Calculations a
Liquid injection rate (cm³/hr) Q = pt*n* 60 * π * D²/4
Velocity of liquid in syringe barrel (cm/min) v₂ = 40/ (60** D²)
Velocity of liquid in syringe needle (cm/min) v₁ = 40/ (60**d²)
