Viscosity can be measured by flow through a thin-bore or
capillary tube if the flow rate is low. For length L, (small)
diameter D« L, pressure drop Ap, and (low) volume flow
rate Q, the formula for viscosity is u = D'Ap/(CLQ), where
C is a constant.
(a) Verify that C is dimensionless. The following data are
for water flowing through a 2-mm-diameter tube which
is 1 meter long. The pressure drop is held constant at
Ap = 5 kPa.

(b) Using proper SI units, determine an average value of C
by accounting for the variation with temperature of the
viscosity of water.
