🔍 Key Concepts

• Tonnes (or tons) Per Inch Immersion (TPI) is the weight required to change a vessel’s draft by one inch • Relationship between salt water density and the constant used in TPI formulas • How waterplane area and unit conversions (feet, inches, tons) affect the numerical constant in the denominator

💭 Think About

• Think about how many inches are in a foot and how that might affect a constant that starts from ‘tons per foot immersion’ and is converted to ‘tons per inch immersion’. • Consider whether the constant in the denominator should be larger or smaller when you convert from a change of one foot in draft to a change of one inch in draft. • Ask yourself which of these numbers (35, 120, 240, 420) is commonly associated with hydrostatic calculations for ships in salt water when using feet and long tons.

✅ Before You Answer

• Verify the standard displacement of 1 long ton in salt water in terms of cubic feet (hint: often approximated as 35 cubic feet per long ton). • Check how many inches are in a foot and how multiplying that by 35 might relate to one of the answer choices. • Confirm that the final constant used for TPI with feet² waterplane area, inches of draft, and long tons matches one of the listed values.
