![calculate the local atmospheric pressure\\ p_{abs}=p_{atm}+p_{gauge}\\p_{abs}=p_{atm}+(p_{wgh})\\185\times10^3=p_{atm}+(1000\times9.81\times9)\\185000=p_{atm}+88290\\p_{atm}=96710pa\\=96.71kpa\\b) calculate the density of the liquid\\s=\frac{p_{l}}{p_{w}}\\0.85=\frac{p_{l}}{1000}\\p_{l}=850kg/m^3\\calculate the absolute pressure\\p_{abs}=p_{atm}+p_{gauge}\\p_{abs}=p_{atm}+p_{lgh}p_{abs}=[96710]+[850\times9.81\times5]\\p_{abs}=138402.5pa=138.4kpa](/tpl/images/0071/9125/08bb7.png)
