Fluids Question

  1. Apr 8, 2010 #1
    1. The problem statement, all variables and given/known data

    Water flows through the pipe in the figure below and exits to the atmosphere at the right end of section C. The diameter of the pipe is 1.98 cm at A, 3.96 cm at B, and 0.792 cm at C. The gauge pressure in the pipe at the center of section A is 1.09 atm and the flow rate is 0.736 L/s. The vertical pipes are open to the air. Find the level (above the flow midline as shown) of the liquid-air interfaces in the two vertical pipes. Assume laminar nonviscous flow.

    Height a = ? m
    Hieght b = ? m

    2. Relevant equations

    velocity = Q/A
    P1 + (.5)*(density)*(v1^2) = P2 + (.5)*(density)*(v2^2)
    P = Po + (density)*g*h

    3. The attempt at a solution

    Pa - Pc = (1.09)(101000) = (1000)(9.81)(height a) ----> height a = 11.2 m

    I'm can't figure out where to begin to find height b.
