Question Number 6767 by Tawakalitu. last updated on 24/Jul/16

A molten  plastic flows out of a tube that is 8.0cm long  at a rate of 13cm^3 /min, when the pressure differential  between the two ends of the tube is 18cm mercury.  find the viscousity of the plastic.   The internal diameter of the tube is  1.30mm.   the density of mercury is 13.6g/cm^3
