Water enters a mixing device at 150 L/s through pipe A, while oil of S.G. 0.8 is forced in at 30 L/s through a pipe B. If the liquids are incompressible and form a homogenous mixture, determine the average velocity and mass density of the mixture leaving through a pipe C of diameter 30 cm. Assume that there is no chemical reaction with the oil and water and that the mixture is incompressible.
