SUMMARY
The discussion centers on calculating the fluid level rise in a manometer using oil and mercury when the pressure in an air tank increases by 0.72 cm of Hg. The relevant equation used is P = rho * gravity * height, where the density of oil is 0.91 g/cm³ and mercury is 13.6 g/cm³. The user attempted to equate the pressures of oil and mercury but struggled to arrive at the correct height for the oil column, estimating it to be around 10.76 cm, which was deemed incorrect. The correct approach involves understanding the density differences and applying the pressure equation accurately.
