Kerosene $($ $=800$ kg$/$m$3)$ flows through the system shown in Fig. The outflow is to the atmosphere. Zo $=20\mathrm{.}0$ m$,$ D$1=10$ cm h$1=4$ cm D$2=7$cm D$3=$ D$4=10$ cm D$5=5$ cm The pipe is horizontal. The fluid in the manometer is mercury. Neglecting friction, calculate $($i$)$ discharge Q $($ii$)$ velocity V$5($iii$)$ Z$3$ and $($iv$)$ h$4.$
