QUESTION $3$

An $8m$ commercial steel pipe with $46cm$ diameter pumps water from a vertical open tank at a flowrate of $3600\frac{m^3}{h}r.$ The pump is positioned $6\mathrm{.}7m$ above the tank, see Figure $3\mathrm{.}1.$ Details of all the minor losses of the pipeline is given in the Table $1$ below. Assume that the density and viscosity of water at the given conditions are $995k\frac{g}{m^3}$ and $0\mathrm{.}0005$ Pa$.$s$,$ respectively. N$.$B$.$ Saturated vapour pressure of water is to be read from steam tables.
