Problem 141E

Problem 141E

The time between failures of a laser in a cytogenics machine is exponentially distributed with a mean of 25,000 hours.

(a) What is the expected time until the second failure?

(b) What is the probability that the time until the third failure exceeds 50,000 hours?

Step-by-Step Solution:
Step 1 of 3

Systemic Circulation -Heart -Arteries -Arterioles -Capillaries -Venules -Veins Factors Affecting Blood Flow -Pressure -force exerted on a liquid unit per area -measured in mm of Hg -Resistance -opposition to force -diameter and length of the blood vessels contribute to resistance -inversely related to blood flow. Blood flow is measured in L/min (CO) -Velocity -Velocity is the distance blood travels in a unit of time (cm/sec) -Laminar vs. turbulent flow -Laminar straight ahead vs. turbulent flow obstructed flow causing whirls and eddys. Can hear murmur on auscultation -Vascular compliance -Vascular compliance is the ability of vessel to take on more value with increased pressure. -Stiffness is opposite of compliance. -Veins have mor
