$4\mathrm{.}5\mathrm{.}4$ The pressure at point $1$ in the parallel pipe system shown in Figure P$4\mathrm{.}5\mathrm{.}4$ is $750$kPa. If the flow rate through the system is $0\mathrm{.}50\frac{m^3}{s},$ what is the pressure at point $2?$ Neglect minor losses. All the pipes are steel with roughness value of $0\mathrm{.}046mm.$ Also, determine the fraction of the flow in each of the parallel pipes and check your solution. Take $v=1\mathrm{.}141{10}^{-6}\frac{m^2}{s}.$
