Problem # $2$ The venturi meter shown in the figure has oil $($SG $=0\mathrm{.}8$; viscosity $=8$ cP$)$ flowing through it$.$ The pressure difference P$1-$P$2$ is $41$bf$/$in$2.$ The diameter at point $1$ is $0\mathrm{.}75$ ft$,$ and that at point $2$ is $0\mathrm{.}25$ ft$.$ What is the volumetric flow rate through this meter? Solve the problem considering the experimental results summarized in the figure below for discharge coefficients $($Cu$)$ for venturi meters. $1$ P $=6\mathrm{.}72*10-4$ lbm $/$ ft$.$s Throat $12$ V$2,$ P$2$ Z$1=$ Z$2$ V$.,$ P Manometer $1\mathrm{.}000\mathrm{.}990\mathrm{.}980\mathrm{.}97$ C $,0\mathrm{.}960\mathrm{.}950\mathrm{.}941456104232|381064568105$ R $=$ V Diplu
