Question

Maintaining a constant pipe wall temperature in some hot­process applications is critical. A new technique that utilizes bolt­on trace elements to maintain temperature was presented in a scientific journal.

• Without bolt­on trace elements, the pipe wall temperature of a switch condenser used to produce plastic has a uniform distribution ranging from 259F to 290F.
• When several bolt­on trace elements are attached to the piping, the wall temperature is uniform from 279F to 288F.

Answer an integer or decimal rounded to four decimal places as needed.

Ideally, the pipe wall temperature should range between 282F to 286F. What is the probability that the temperature will fall in this ideal range when no bolt­on trace elements are used? 0.1290

When the temperature is 278F or lower, the hot liquid plastic hardens (or plates), causing a buildup in the piping. What is the probability of plastic plating when no bolt­on trace elements are used? 0.6129
