1. The problem statement, all variables and given/known data If you have a manometer with a 70cm tall water column, what is the largest pressure that can be measured? Assume that the densities of water and mercury are 1000 kg/m3 and 13 600 kg/m3 respectively 2. Relevant equations P=pgh+Patm 3. The attempt at a solution I've attempted this question and am getting an answer of 801mmHg however the answer is 51.5mmHg. My attempt: P=pgh+Patm =(1000 x 9.8 x 0.70) + (1 x 105) =106860Pa And then to convert it to mmHg since 101325Pa=760mmHg I went (106860 x 760)/101325 =801mmHg Can someone please help with where I'm going wrong here?
