To determine the amount an 80-foot run of Schedule 40 PVC will expand due to temperature changes from -5°F to 100°F, it’s important to understand how thermal expansion works for materials. The coefficient of linear thermal expansion for PVC is approximately 3.0 x 10^-5 inches per inch per degree Fahrenheit.

First, calculate the temperature change:

  • From -5°F to 100°F is a change of 100 - (-5) = 105°F.

Next, apply the formula for linear expansion:

Expansion = original length × coefficient of thermal expansion × temperature change.

  • The original length is 80 feet, which is 80 x 12 = 960 inches.

Now, plug in the values:

  • Expansion = 960 inches × (3.0 x 10^-5 inches/inch/°F) × 105°F.

  • Expansion = 960 × 3.0 x 10^-5 × 105.

Calculating that gives:

  • Expansion = 960 × 0.000030 × 105 = 0.3024 inches (this seems to be the counting error from steps, we should re-calculate the values correctly).

Upon correctly calculating the values for thermal expansion,
