1. Find , the speed of the fluid in the left end of the main pipe. Express your answer in terms of h_1, h_2 , g , A_1, A_2. 2. Bernoulli and continuity equations 3. p_1 = rho*gh_1 p_2 = rho*gh_2 p_2 = p_1 + 0.5rho*v_1^2 + 0.5rho*(A_1/A_2)^2 * v_1^2 I know those are correct. Substituting for p_1 and p_2, and solving for v_1 I obtain: 2g(h_2 - h_1) / [1-(A_1/A_2)] all that under a square root. No idea why I am getting it wrong. Should h_2 - h_1 just be h??
