10.In an experiment with Poiseuille’s apparatus the volume of water coming out per second is 8 cm3 through a tube of length 0.62 m and of uniform radius 0.5 mm. The pressure difference between the two ends of the tube is equal to 3.1 cm of Hg. You can use the Poiseuille’s formula to calculate the coefficient of viscosity   (4)
