EXERCISE $3$

A pump $P$ moves a flow rate $Q=\frac{751}{s}$ of naphtha $)=(6{10}^{-6}\frac{m^2}{s}$ from tanks A to tank B$.$ The distance of the liquid levels in the two tanks is $Y=80m$ the lengths and diameters of the pipes in and out of the pump are, respectively,: $L_1=50mD=0,4m($from tank $A$ to Pump$)$; $L_2=700m{D}_2=0,3m($from tank $B$ to Pump$).$ The absolute roughness of the pipes is ${}_1={}_2=0,0008m.$ Calculate the power of the pump assuming its efficiency $=85\%.$ Do the calculations first not including and then including minor head losses. Assume the flow regime to be fully turbulent. Draw $($and explain the meaning of$)$ the HGL and EGL.
