Q$4)$ In the system shown below, viscous oil flows from reservoir $A$ to reservoir $B.$ The oil has a flow rate of $300\frac{L}{s},$ a density of $0\mathrm{.}8\frac{g}{c}{m}^3,$ and a kinematic viscosity of ${10}^{-3}\frac{m^2}{s}.$ If the length of the pipe is $10m$ and the diameter is $0\mathrm{.}40m,$ determine the $H$ level difference between the two reservoirs by considering the local and continuous head losses. Draw the energy and piezometer lines of the system $(30$P$).$
