QUESTION $2$

Water at the temperature of $20C$ is flowing inside a commercial steel pipe with an

internal dlamerer of $170mm$ ant roughness fraction of $\frac{0\mathrm{.}04}{b}ar(6m).$ The pipe fias a fength

of $150m$ and the pressure dilference to overcome friction loss is $55$kPa, calculate the

allscharge llow rate. Perform two frials only.
