🔍 Key Concepts

• Use the separating temperature axis at the bottom/top of the graph to locate 167°F and read vertically • Identify the correct specific gravity line for the oil (0.98 kg/dm³) on the vertical axis • Follow the nearest regulating ring (Ø) curve that passes through the intersection of temperature and specific gravity

💭 Think About

• When you go up from 167°F, which regulating ring curves are closest to the 0.98 kg/dm³ point? • Is the oil point (solid line) above or below each nearby Ø-curve, and which curve best fits that intersection? • Are you reading the curves for oil (solid line) and not the water (dashed) curve when matching SG and temperature?

✅ Before You Answer

• Confirm you are using the solid oil curve, not the dashed water curve, at 0.98 kg/dm³ • Double-check that you converted 167°F to the correct position on the temperature scale (between 160°F and 170°F marks) • Verify the ring size label (Ø mm) printed on the curve that most accurately passes through the intersection of 167°F and 0.98 kg/dm³
