15 & 16 - Internal Flow Water at 10°C (p=999.7 kg/m3 and μ = 0.001307 Pa·s) is flowing steadily in a 0.12-cm- diameter, 15-m-long pipe at an average velocity of 0.9 m/s. Determine (a) the pressure drop, (b) the head loss, and (c) the pumping power requirement to overcome this pressure drop. [(a) 392 kPa, (b) 40.0 m, (c) 0.399 W].
