Glycerine flows steadily through a horiz...

Glycerine flows steadily through a horizontal tube of length 1.5m and radius 1.0 cm . If the amount of glycerine collected per second at one is `4.0xx10^(-3)kgs^(-1)` , what is the pressure difference between the two ends of the tube ? (Density of glycerine `=1.3xx10^(10^(3)kgm^(-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]
