a 5-mm-diamter capillary tube is used as a viscometer for oils. When the flow rate is 0.071 m3/h, the measured pressure drop per unit length is 375 kPa/m. Estimate the viscosity of the fluid. Is the flow laminar? Can you also estimate the density of the fluid?

6.14 Water at 20°C is to be siphoned
through a tube 1 m long and 2 mm in
diameter, as in Fig. P6.14. Is there any
height H for which the flow might not be
laminar? What is the flow rate if H = 50 cm?
Neglect the tube curvature.
