Key Insights

• 🫗 The specific gravity of a substance can be used to calculate its density relative to a standard liquid.
• ↔️ Balancing the left and right limbs of a differential manometer allows us to determine the pressure difference.
• 🙈 The density of a fluid affects the pressure it exerts in a column, as seen in the calculations involving oil and mercury.
• 🛢️ The specific gravity of oil is used to simplify calculations involving pipelines containing the same fluid.

Summary & Key Takeaways

• A pipe contains oil with a specific gravity of 0.9, and a differential manometer connected at two points shows a 15 cm difference in mercury level.

• The density of oil can be calculated using its specific gravity and the density of water.

• To find the pressure difference at the two points, the left and right limbs of the differential manometer are balanced using the heights of oil and mercury.
