In a certain medical application, water at room temperature and pressure flows through a rectangular channel of length L = 22 cm, widths= 2.6 cm, and gap thickness b = 0.3 mm as shown in the diagram below. The volume flow rate is sinusoidal Q sin (21ft ). Assume that v =1 x 10 m2/s and p = with amplitude Q = 0.50 mL/s and frequency f = 20 Hz, i.e., Q = 0.001 Pa-s.

Required information
In a certain medical application, water at room temperature and pressure flows through a rectangular channel of length L =
22 cm, width s = 2.6 cm, and gap thickness b = 0.3 mm as shown in the diagram below. The volume flow rate is sinusoidal
with amplitude Q = 0.50 mL/s and frequency f = 20 Hz, i.e., Q = Q sin (2Tft ). Assume that v = 1 x 10 6 m2/s and u =
0,001 Pa-s.
b.
Calculate the maximum Reynolds number (Re = Vb / u) based on maximum average velocity and gap thickness. Channel flow like this
remains laminar for Re less than about 2000. If Re is greater than about 2000, the flow will be turbulent.
The Reynolds number is
