Oil (of density 850 kg/m3) circulates through a horizontal hose system inside an olive oil filling machine. First, the oil flows at a speed of 8.0 m/s through a hose with a radius of 1.0 cm. An oil manometer indicates a pressure of 7.0 × 104 Pa. A horizontal hose elbow connects the 1.0-cm-radius hose to a smaller hose with a radius of 0.75 cm. Calculate the pressure inside the smaller hose.
