Homework Help: Dynamic Fluid Question

  1. Dec 9, 2015 #1
    1. The problem statement, all variables and given/known data
    In ideal flow, a liquid of density 810 kg/m3 moves from a horizontal tube of radius 1.60 cm into a second horizontal tube of radius 0.800 cm at the same elevation as the first tube. The pressure differs by ΔP between the liquid in one tube and the liquid in the second tube.
    (a) Find the volume flow rate as a function of ΔP.

    2. Relevant equations

    3. The attempt at a solution
    Completely lost, not sure where to start.
