A fluid with a density of $900k\frac{g}{m^3}$ flows from a large tank at a higher location to a tank at a lower

location in a $150-m-$long,$8-cm-$diameter pipe. Determine the height difference between the tanks

if the volumetric flow rate is $0\mathrm{.}6\frac{m^3}{m}in.$ Take the viscosity of the fluid as $0\mathrm{.}002$ Pa$.$s$.$ Use

Colebrook Equation if necessary. Solve the problem for the following two cases.

A$]$ The pipe material is commercial steel $(=0\mathrm{.}045-mm).$

B$]$ The pipe is plastic and there are $5$ threaded bends $(K_L=0\mathrm{.}9$ for each$)$ and $5$ fully open angle

valves for each A fluid with a density of $850$kg $/$ m$^3$ flows from a large tank at a higher location to a tank at a lower location in a $120-$m long, $6-$cm diameter pipe. Determine the height difference between the tanks if the volumetric flow rate is $0\mathrm{.}5$m$^3/$ min. Take the viscosity of the fluid as $10^-3$Pa$.$s$.$ Use Colebrook Equation if necessary. Solve the problem for the following three cases. Comment on your results. A$]$ The pipe material is galvanized iron $(\backslash$epsi $=0\mathrm{.}15-$mm$).$ B$]$ The pipe is glass. C$]$ The pipe is plastic. Also, there are $7$ threaded bends $($ K$\_$L$=0\mathrm{.}9$ for each$)$ and $5$ fully open angle valves $($K$\_$L$=5.$ for each$)$ in the system.
