1. The problem statement, all variables and given/known data Mercury is added to a cylindrical container to a depth d and then the rest of the cylinder is filled with water. If the cylinder is 0.8 m tall and the pressure at the bottom is 1.3 atmospheres, determine the depth of the mercury. (Assume the density of mercury to be 1.36 104 kg/m3.) 2. Relevant equations Ptotal=Patmosphere+Pwater+Pmercury P=density x g x height 1 atmosphere=1.013e5 Pa density of water=1 x 103 kg/m3 pressure of atmosphere=1 atm 3. The attempt at a solution I first subtracted out the pressure of the atmosphere, so .3 atm=Pwater + Pmercury .8m=Hwater + Hmercury Pmercury=1.36 x 104 x 9.8 x Hmercury Pwater=1 x 103 x 9.8 x Hwater I am having difficulty putting all 4 of these equations together. I feel like there is substitution needed, but which equations should I use?
