Question

# A Ventouri tube with a narrowing diameter d[m] was inserted into the pipeline with the diameter D[m). On each of the hoses there is a pressure gauge connected with one arm to the pipeline.The other arm of both gauges is open. According to the manomoters indications, there is an overpressure in the lines, equal to H, (m] and H,[m), respectively. The density of the flowing medium is p[kg/m'], the density of the manometric liquid is pe[kg/m*J. Calculate the speed of the flowing medium in a pipe with a diameter D[m). D=0,05+0,001 \cdot N r[m]= d=0,02+0,002 \cdot \mathrm{Nr}[\mathrm{m}]= H_{1}=0,12[m] H_{2}=0,04[m] \rho=1000\left[\mathrm{~kg} / \mathrm{m}^{3}\right] \rho_{C}=13579\left[\mathrm{~kg} / \mathrm{m}^{3}\right] Fig: 1 Fig: 2 Fig: 3 Fig: 4 Fig: 5 Fig: 6 Fig: 7 Fig: 8
