2. A 'light' liquid ( SG=0.95 ) flows at an average velocity of 10m/s through a horizontal smooth tube of 5cm diameter. The fluid pressure is measured at 1m increments along the pipe with data given in the table below. Estimate from this data; a. the total head loss ( m), b. the wall shear stress (N/m2) in the fully developed section of the pipe, and c. the overall friction factor. Aherolute visersitv N/m2
