A manufacturer of disk drives for notebook computers wants a MTBF of at least 50,000 hours. Recent test results for 15 units were one failure at 12,000 hours, one at 20,000 hours, and one more at 48,000 hours. The remaining units were still running at 60,000 hours.
Determine the following:
Number of failures per unit-hour of operating time = failures per hour (round your response to eight decimal places).

Industry: Food & Beverage Location: Topeka, KS ROI: 700% Payback Period: 3 months CO₂ savings: 20k+ metric tons / year Coverage: 100% Challenge Like most food & beverage manufacturers, this customer utilizes steam in the production of several product lines. Ensuring the smooth operation of its steam system is an important aspect of its maintenance strategy due to the system’s potential impact on the plant’s overall operating costs; a poorly functioning steam system can significantly reduce uptime, energy efficiency, and the safety profile of a given plant. With steam trap failure representing one of the highest risks to a steam system, maintenance of these mechanical relief devices is of paramount importance.
