Glycerine flows steadly 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]

Explanation

`9.8 times 10^2 Pa` (The reynolds number is about 0.3 so the flow is laminar)
