1. The problem statement, all variables and given/known data The two water reservoirs shown in the figure are open to the atmosphere, and the water has density 1000 kg/m3. The manometer contains incompressible mercury with a density of 13,600 kg/m3. What is the difference in elevation h if the manometer reading m is 25.0 cm? 2. Relevant equations Bernoulli's Equation Atmospheric pressure + 1/2(density of fluid)(speed^2) + (density)(gravity)(change in height) = constant Continuity Equation (density)(speed)(area) = constant [all fluids] (speed)(area) = constant [incompressible fluids] 3. The attempt at a solution I have no idea.
