Question: Water at 10°C (ρ = 999.7 kg/m3 and µ = 1.307 × 10-3 kg/ms) is flowing in a 0.20-cm-diameter 15-m-long pipe steadily at an average velocity of 1.2 m/s. Determine
(a) the pressure drop and
(b) the pumping power requirement to overcome this pressure drop. Assume flow is fully developed. Is this a good assumption?
