About this document
Optimal Insulation Thickness for Cost Efficiency by rshafizan is a document available to read on EtoBox.
The document describes optimizing the thickness of insulation (X) on a steam pipe to minimize total annual costs. It gives the fixed and heat loss costs as functions of X, then calculates the optimum thickness (X*) as 0.0305 meters by taking the derivative of total cost and setting it equal to zero. It confirms this is a minimum by showing the second derivative is positive at X*. The basic trade-off is between the direct cost of more insulation and the indirect savings from reduced heat loss.
