A fluid has a kinematic viscosity ν=15x10-6 m2 s-1 and a density ρ=1 kg m-3. In a given industrial application we have a straight, circular pipe of radius 0.1 m and length 11.8 m. A pressure drop of Δp=4.8 Pa is imposed to drive the flow. Assuming a fully developed and steady state flow in the entire pipe, find the wall shear stress magnitude in SI units? Give your answer to three decimal places.
