Water at $10\backslash$deg C $($p $=999\mathrm{.}7$ kg$/$m$\text{'}$ and M $=1\mathrm{.}307$ x$10-3$ kg$/$ms$)$ is flowing in a $0\mathrm{.}20-$cm$-$diameter, $15-$m$-$long pipe steadily at an average velocity of $1\mathrm{.}2$ 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? Answers: $($a$)188$ kPa, $($b$)0\mathrm{.}71$ W
