Section II: Degradation Data Analysis of Pipes Using Weibull++ Pipes age due to corrosion, causing the pipe thickness to decrease, eventually rupturing due to internal pressure. The design is safe up to 10 mm pipe thickness. The pipe thickness was recorded at 16 locations, with measurements given below, and time in days.

Due to how equations for the degradation models are formulated in Weibull++, it is wise to consider the suitability of the given thickness data, as well as wear data. Convert measured thickness to wear using the equation: wear = constant - measurement (Hint: Adjust constant to consider different sets of "wear' data that begin at Omm, 1mm or 2mm.) Assess the suitability of each set of data in Weibull++, by considering their fit to the linear and exponential degradation models. Use the parameter to fill up the table below.

Determine the Weibull distribution parameters for time-to-failure caused by the degradation. (Use RRX in your analysis). Weibull distribution parameters: 4. Pipe ruptures are highly undesirable, costing an estimated $1.5 million. A preventive maintenance to replace the pipe costs $120,000 a. Based on the Weibull distribution parameters in Q3, is the preventive maintenance justified? If yes, determine the recommended interval for replacement (preventive maintenance), and show a plot of the planned replacement cost per unit time vs time. Explain whether replacement PM is justified, and why. Optimum interval for replacement (PM): Plot of the planned replacement cost per unit time vs time. b. Determine percentage of pipes that would have reached 10 mm by the recommended interval for replacement 5. Besides being known to be safe to 10 mm thickness, the pipes are also known to have a high chance of failure at 6 mm thickness. Determine how long it will take for a pipe to reach 6 mm thickness. (Hint: Re-run degradation analysis to 6 mm critical thickness and show the degradation plot).
