Applying fluid dynamics: Putting it all together

Engineers use a venturi meter to measure the speed of a fluid traveling through a pipe (see Figure P11.37). Positions 1 and 2 are in pipes with surface areas A₁ and A₂, with A₁ greater than A₂, and are at the same vertical height. How can you determine the relative speeds at positions 1 and 2 and the pressure difference between positions 1 and 2?
