owint \( r \) a \( 0.35 \mathrm{~m} \) Nighe, the pressure is \( p_{2}=1,20 \times 10^{4} \mathrm{~Pa} \) and the pipe dameter is \( 4 . \mathrm{co} \mathrm{cm} \). (w) Find the spted of faw (in m/s) in the fower section. (0) Find the soeed of naw (in mis) in the upper section. (c) Find the volume flew rate (in \( \left.m^{3} / 3\right) \) thisogh the pipe. Oil with a density of \( 890 \mathrm{~kg} / \mathrm{m}^{3} \) moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is \( P_{1}=1.95 \times 10^{4} \mathrm{~Pa} \), and the pipe diameter is \( 8.00 \mathrm{~cm} \). At another point \( y=0.35 \mathrm{~m} \) higher, the pressure is \( P_{2}=1.30 \times 10^{4} \mathrm{~Pa} \) and the pipe diameter is \( 4.00 \mathrm{~cm} \) (a) Find the speed of flow (in \( \mathrm{m} / \mathrm{s} \) ) in the lower section. \[ \mathrm{m} / \mathrm{s} \] (b) Find the speed of flow (in \( \mathrm{m} / \mathrm{s} \) ) in the upper section. \[ \mathrm{m} / \mathrm{s} \] (c) Find the volume flow rate (in \( \mathrm{m}^{3} / \mathrm{s} \) ) through the pipe. \[ \mathrm{m}^{3} / \mathrm{s} \]
