An oil of density 892 kg/m³ is flowing in a pipe having an internal diameter 5cm. This pipe is connected to another one with diameter 7.5cm which branches into two smaller pipes each one having a diameter of 3.75cm. If the flow rate in the first pipe is 1.388 x 10 m³/s, calculate: a- The mass flow rate in the first pipe and in the branches of the second pipe. b- The average velocity in the first pipe and in the branches of the second pipe.
