Problem 3 (ii): Water at a temperature of 15 °C is flowing steadily in a 6 cm diameter, 25-meter long pipe at an average velocity of 6.0 m/sec. The flow is fully developed. The cross-section is circular. For the wall surface condition where the wall has become degraded due to pitting and deposits such that there is a surface roughness with a height of 0.3 millimeters, find the following:a) The Reynolds number. State whether laminar or turbulent flow is expected.b) The Darcy friction factor, ?.c) The pressure drop over the length of the pipe, and the corresponding head loss.
