The failure rate for a high-speed fan is given by: () = (2 x 103 x 10-6)/hr where t is in hours of operation. The required design life is 100 hours. Question 14: If, by preventive maintenance, the wear (i.e., time based) contribution to the failure rate can be eliminated, the revised design-life reliability is closest to: a. 0.991 O b.0.965 c. 0.973 O d.0.980 The failure rate for a high-speed fan is given by: () = (2 x 103 x 10-6)/hr where t is in hours of operation.
