![Calculations
Liquid injection rate (cm?/hr) Q = pt * n * 60 * n * D?/4
Velocity of liquid in syringe barrel (cm/min) vb = 4Q/ (60 * n * D²)
Velocity of liquid in syringe needle (cm/min) vn = 4Q/ (60 * T * d²)
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 cmeach 3 hour, injection time = 1
min).
