Glycerine flows steadily through a horizontal tube of length 1.5m and radius 1.0cm. If the amount of glycerine collected per second at one end is 4.0 x 10-3KgS-1, what is the pressure difference between the two ends of the tube? Density of glycerine = 1.3 x 103Kgm-1  and viscosity of glycerine = 0.83 Nsm-2 (You may also like to check if the assumption of laminar flow in the tube is correct.)
