1. The problem statement, all variables and given/known data A block of mass 20 g sits at rest on a plate that is at the top of the fluid on one side of a U-tube as shown below. The U-tube contains two different fluids with densities ρ1 = 1070 kg/m3 and ρ2 = 650 kg/m3 and has a cross sectional area A = 4.6 * 10-4 m2. The surfaces are offset by an amount h as shown. 2. Relevant equations I thought the equation I wanted to use was h = [(p1-p2)/p1]*h2, but this isn't correct. 3. The attempt at a solution Based on what I thought the equation was, I got .0785m, which isn't right. I used [(1070-650)/1070] * .2 Any help would be appreciated.
