How much will a 40' run of 2" Spears Flamegaurd CPVC Fire Sprinkler pipe expand if the expected ambient temperature is 60 degrees?

The expansion of a pipe due to temperature changes can be calculated using the coefficient of thermal expansion for the material. For CPVC, the coefficient is typically around 5.0 x 10^-5 per degree Fahrenheit.

To determine the expansion of a 40-foot run of 2" CPVC pipe when the temperature changes, you first need to convert the length into inches (since there are 12 inches in a foot). A 40-foot length amounts to 480 inches.

Using the formula for thermal expansion, which is:

Expansion = Original Length × Coefficient of Expansion × Change in Temperature

If we assume that the temperature rise is from a standard temperature (let's say 32 degrees Fahrenheit, which is a common reference) to 60 degrees, the change in temperature would be 28 degrees Fahrenheit.

Now, we can input the values into the formula:

Expansion = 480 inches × 5.0 x 10^-5 per °F × 28 °F

This calculation yields an expansion of approximately 0.672 inches, which can be rounded to 0.75 inches, depending on the precision of the given values. However, when rounding further or depending on specific commercial practices, the answer might indicate that the
