Linear Trend Extrapolation

First Data Point

X₁ Value

Y₁ Value

Second Data Point

X₂ Value

Y₂ Value

Extrapolation Point

X Value (extrapolate to)

Enter X value beyond the data range to extrapolate Y.

Formula

Y = Y₁ + (X - X₁) × (Y₂ - Y₁) / (X₂ - X₁)

Y = Extrapolated value

(X₁, Y₁), (X₂, Y₂) = Known data points

X = Value to extrapolate at

Common Applications

Performance Prediction
Equipment performance beyond tested ranges
Trend Analysis
Future values based on historical data
Property Estimation
Material properties at extreme conditions

Important Notes

Extrapolation accuracy decreases rapidly outside data range
Linear extrapolation assumes constant trend - verify reasonableness
Physical limits may invalidate extrapolated values (e.g., negative pressure)
Consider safety factors when using extrapolated data for design
Multiple data points provide better extrapolation confidence
