2. The Colebrook equation for the friction factor in a filled pipe is: E/D 2.51 20910 3.7 Ref where fis fraction factor, E D is the relative roughness of the pipe material, and Re is the Reynolds number. For a Re=1000 and aD-0.3 find the friction factor using the Bisection method with your initial brackets at =0.15 and x,-0.30. Use Python with if statements for the xrxl or xu criteria, and a while loop to perform the procedure while the approximate error (EA) is less than 1%
