If the diameter of a pipe is reduced by 50%, how much do you expect the velocity to change?

A pipeline with a diameter of 12 inches carries a liquid with a specific gravity of0.86 at a velocity of 10 ft/s. Determine the liquid velocity and the mass flux if the pipe diameter is reduced to 8 inches at another section.
