A horizontal pipeline carries 10,125 m^3 of oil every hour. Along the pipeline where the radius is 60 cm, the oil pressure is 170 kpa. The density of the oil is 800 kg/m^3. What is the oil's speed in the pipeline where the radius is 60 cm? What is the oil's speed in the pipeline where the radius is 25cm? What is the oil pressure in the pipeline where the radius is 25 cm?
