SUMMARY
The discussion centers on calculating absolute pressure at point P1 using the equation P=Patm + dgh. The user converted densities to kg/m³ and calculated P1 as 99.204 kPa, which includes contributions from both water and mercury columns. The arithmetic was confirmed as correct, but the final answer should be expressed in mm Hg rather than kPa. The conversion process and the importance of unit consistency in pressure calculations were emphasized.
PREREQUISITES
