Aperson with no experience in fluid mechanics wants to estimate the friction factor for 1-in.-diameter galvanized iron pipe at a reynolds number of 12000. the person stumble across the simple equation of f = 64/re and use this to calculate the friction factor. consider the problem with this approach and estimate percentage of their error (fa-f)/fa, where fa – actual friction factor.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
