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 $4.0 \times 10^{- 3} kg s^{- 1}$ , what is the pressure difference between the two ends of the tube? (Density of glycerine $= 1.3 \times 10^{3} kg m^{- 3}$ and viscosity of glycerine $= 0.83 Pa s$ ). [You may also like to check if the assumption of laminar flow in the tube is correct].
