Experiment Data
Take the following data for the syringe injection pump
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
Liquid injection rate (cm /hr) Q = pt *n * 60 * n * D²/4
Velocity of liquid in syringe barrel (cm/min) v = 4Q/ (60 * T * D?)
%3D
Velocity of liquid in syringe needle (cm/min) vn = 4Q/ (60 * n * d?)
%3D
Find the rotation velocity of lead screw n and the velocity of liquid in syringe needle if the
required injection dose is
1. 10 cm3 in 3 hours
(continuous injection)
2. 20 cm3 in 12 hours
(discontinuous injection, 5 cm³each 3 hour, injection time = 1
min).
Discus the results briefly.
