Q$4.$SOLVE USING HAND Water flows from the container shown in the figure. Determine the minor loss coefficient needed in the valve if the water is to bubble up $7\mathrm{.}5cm$ above the outlet pipe. Given that $K_{\text{e}\text{n}\text{t}\text{r}\text{a}\text{n}\text{c}\text{e}}=0\mathrm{.}5,k_{\text{b}\text{e}\text{n}\text{d}}=0\mathrm{.}19,$ friction factor within the pipes is $f=0\mathrm{.}04.$
