🔍 Key Concepts

• Use the ball float chart to find operating force from the float ball in pounds. • Match the ball diameter line (9 inches) with the specific gravity line (1.0) to get the force. • Compute torque as force times the effective float arm length (27 inches); result will be in inch‑pounds.

💭 Think About

• On the chart, where exactly do you read the operating force once you’ve located the correct ball‑diameter line and specific gravity? • After you read the force value from the chart, how do you convert that into torque using the given arm length? • Which of the choices is closest to the product of the chart force (from the 9-inch, SG 1.0 point) and the 27‑inch arm?

✅ Before You Answer

• Be sure you are using the 9-inch diameter line, not a nearby one (like 8" or 10"). • Confirm you are reading the correct horizontal scale in pounds of force along the bottom of the chart. • Verify that your final torque is computed as (force in lb) × (27 in) and expressed in inch‑pounds, not foot‑pounds.
