9.13 Glycerine flows steadily through a horizontal tube of length 1.5 m and radius 1.0 cm . If the amount of glycerine collected per second at one end is 4.0×10−3 kg s−14.0 \times 10^{-3} \mathrm{~kg} \mathrm{~s}^{-1}, what is the pressure difference between the two ends of the tube ? (Density of glycerine =1.3×103 kg m−3=1.3 \times 10^{3} \mathrm{~kg} \mathrm{~m}^{-3} and viscosity of glycerine =0.83 Pa s=0.83 \mathrm{~Pa} \mathrm{~s} ). [You may also like to check if the assumption of laminar flow in the tube is correct].
